My Peavey bass has had FOUR previous owners, and had not been properly cared for in a few ways. I knew Justin through mutual friends and decided he was the best person to care for her. Dropped her off, Justin explained to me up front what should be done and how much it would cost. The Jack was ruined, wiring was not connecting enough for the sound to pick up. About 5 days later it was ready for me to pick up, he explained what he did and why, said it played great and boy did it! Along with the Jack replacement, he did a full setup and worked on the bridge so the strings wouldn’t buzz as much when I played. Needless to say, it plays AMAZING now, and I’m finally realizing I’m not bad at playing bass, I just didn’t have one in proper shape to be a new player in the learning process. It feels and sounds great, affordable pricing and kind customer service.

Justin has worked on no less than 5 of my guitars. Everything from basic tune/set ups all the way to builds. He always does outstanding work, is very transparent thru the process and does the work in a timely matter. Highly recommned.

Justin does the Denver music scene right with his great prices and 5-star service!! Lots of guitar players come to my shop, and there is nothing more frustrating than a guitar that doesn’t play right, so all my inventory gets setup before being listed for sale. All the guitars I’ve brought to Justin have come back playing like butter and exactly the way I hoped they would. Reasonable pricing and super-fast turnaround time too!! You’ll be a better player if Hackl works on your axe...AWESOME!!

Best in the whole city, and Im picky.

Justin has the tender hands of a angel but with the strength of a demigod. His skills with an axe are second to none, and his eyes burn into your soul with the fiery passion of a thousand suns. If i knew how to play guitar or even owned one i would go there even more often, but for now the spiritual ecstasy i receive by pressing my nose up against the window while watching him work will have to suffice.

Justin is the best! Customer for life. Great service. He knows what he’s doing. He’s done everything for me from guitar set ups to replacing pick ups to neck repair. Always on time. Always reasonable prices.

Justin does outstanding work. He is incredibly knowledgeable and efficient with guitar repairs and modifications. Brought in a Martin acoustic with buzzing strings, he immediately identified the problem and solution. I got my guitar back in just a couple days and it literally sounds better than the day I took it out of the box. All for an exceedingly fair price. I could not be more happy with this service. I unequivocally recommend Hackl Guitars for any guitar repairs or modifications you may require.

Justin is the most fair, and honest priced quality repair and custom shop you’ll find in CO bar none. He’s been living here and playing guitar his whole life. Support local, support this shop.

Great work at an affordable price. Justin is also very honest, which speaks volumes. I took in a guitar to get fixed that he found did not need any work in the diagnostic phase. Instead if keeping that to himself and pretending to do work that didnt need to be done he told me up front.10/10, would recommend Hackl guitars to anyone who needs repairs done.

Fantastic service, affordable and quick. Brought my 65 mustang back to life, highly recommend!

Justin performed setups and repairs on three of my guitars. His work was flawless and he is fast. Incredibly easy to get ahold of. His shop is behind his house and it is obvious he takes great pride in his work. Just an outstanding artisan!

Amazing work. Justin made my Warlock sound like it did when I first got it. Great shop and great service.

The work done by Hackl Guitars on every piece I own plus a custom guitar he built for me has been outstanding. I highly recommend Hackl for any work you may need to be done.

I asked Justin to set up 2 of my guitars right before the holidays. Both were set up perfectly and now play SUPER smoothly! He does very nice work and they were ready when promised.Thanks Justin!!

Took a few guitars here awhile back and had a good experience on the set ups for those instruments. He got my longest owned strat back in good playable condition after I previously made some big adjustments to it to accommodate some very thick strings. Would certainly recommend his services at the reasonable price point he offers.I did have one issue though. That strat had some chips in the finish, naturally acquired over many years of playing and gigging. He touched some of them up with a paint marker. Some people I’m sure would appreciate him doing this with no additional charge, but if I would have known I would have asked him not to. Those blemishes are character, and tell a story. They show the work this instrument has put in to entertain others. I am still a little upset by this and wish he would have asked before doing so. A small gripe, but overall his customer service and abilities are excellent, so I’m happy to still give 5 stars

Hackl Guitars fixed the crack in an acoustic guitar for me and I couldn’t have been happier. Definitely recommend!

Great value, great work, very quick repair time. If you need work on you guitar or bass, Hackl Guitars is the place.

Justins a cool dude who can do proper repair work and do it well. He brought my secondhand Yamaha acoustic back to life even though it was coming apart, I am convinced that if a fix is possible, Justin Hackl can do it.

Phenomenal job Justin does. Super easy to get a hold of. His workspace is awesome and you can tell he truly enjoys and cares about his work. Ill always bring my guitars here for set ups, repairs and whatever else they might need!

Decided to check him out after reading all the good reviews and was not disappointed. Great work and quick turnaround time! Hackl Guitars will be the only place I take my guitars for any future repairs or adjustments.

Brilliant guitar shop! could not respect the owner more, great sense of humour!

Justin was quick to reply to email inquiries and patient when my strings didnt come in the expected time frame. Once my guitars were delivered Justin made sure to update me on extended repair time but the short wait was worth it. When returned my acoustic guitar and 5string bass absolutely sung! Great service at a great value, Hackl is your one stop shop for setups and repairs.

Had an electronics repair and a fresh setup on a semi custom Ormsby headless, I felt very confident in Justins expertise dropping it off, got it back in 2 days. Justin is awesomely knowledgeable to chat with and open to personal preferences, casual, personable, professional.

Justin is very knowledgeable about guitars and was easily able to help me with my guitar. He listened carefully and didn’t blow off any concerns I had. The problem was not actually a problem, but something I just didn’t understand. He assured me the mistake is easy to make. When my guitar needs actual work, as it will eventually need due to time and use at some point, I’m taking it to Justin.

Justin worked on a new Fender neck I bought for a custom build. The nut was too high and some frets were out of line. Justin fixed those and did a full set-up, now the guitar plays like it should. Nice job!

Place is the best. If youve never seen the best, come here, and then you can see the best. Also you can meet the best.

Justin did an amazing job with my super old guitar! He was very open and had great communication with me. I know very little about guitars but he helped to understand all the steps and the work. The price was great!

Justin is the best. Super fast and the nicest guy. Won’t go anywhere else in Denver.

Excellent service! I brought my Tele in for basic setup to Hackl Guitar. It was ready as promised. Justin had good communication. It felt easy to ask questions. My guitar feels better now. Thanks Justin!

I commissioned Mr. Hackl to make me a custom bass after mine got stolen. He became my go to guy for set ups and all things related. My bass is killer and everyone asks me about it. I call it a Hacklbacker. It sounds better than my 84 Richenbacker that was stolen.

Justin has worked on something like 6 of my guitars, he does top quality work at a very fair price. Ive dealt with him for years, and hes been fair, transparent, honest, and accountable in all of our interactions. Ive never gotten an instrument back from him in a condition that I was unhappy with. Its a mistake to take your guitar anywhere else.

Justin is the man! Really great work, and brought my acoustic back from a long time without any adjustments or maintenance. Highly recommended!

It seems like Justin hardly needs another 5 star review to add to all those he already has! - but I want to add my voice to the total anyway... He is friendly and very competent, quick, and charges a very fair price. The work I needed was not super complicated, but it was important to me. I felt he showed respect and enthusiasm for that, and did a great job.

Justin was awesome. Fair price, excellent service. Cool little shop!1st visit in a couple years. Had what turned out to be a simple repair. Justin took care of it on the spot and was more than fair with price. Another excellent experience from a pro!

Justin installed pickups and did an excellent job! I wont let anyone else do work on my guitar. Awesome setups. His custom builds are incredible, too.

Fast and Friendly. Got some fret buzz fixed - guitar sounds great!

Justin re-fret my Fender MIJ 86 telecaster with stainless steel frets back in June of this year (2017) and did a fantastic job. He also replaced the plastic nut with a bone nut. The guitar plays and sounds better than it ever has. The work was done at a very fair price and I would not hesitate to have him work on any of my other guitars. To top it off, hes a nice guy too.Thanks Justin

Justin is friendly, responsive, and does great work at a fair price. I originally took my acoustic guitar to him after the neck broke and he did a great job repairing it. Actually I got it back in better playing shape than before! I’ve taken it back since then for minor adjustments and have always been pleased with the results.

Justin has done work on four or five of my guitars over the past several months, including set-ups, custom nuts and electronics upgrades. Each guitar Ive brought to him now play and sound better than they ever have before. He really knows how to bring out the best in every instrument. Plus hes just a cool, down to earth guy. Dont spend money on any more gear until youve had your instrument set up properly by someone like Justin (I have yet to find anyone better than him though!) Hackl Guitars FTW!

Justin is truly the best, most down to earth tech Ive met in Denver. Fixed my Les Paul wiring with clean, no nonsense soldering. Dont mess around with the other shops! Go to Hackl

Justin is a gem if you need work done on your guitar. He actually cares, will take the time to talk to you and see specifically what you want, does quality work, and very very affordable. I had my him work on a semi hollow for me, installing new pick ups, saddles, fretwork, and set up. I will just say he saved me a pretty penny when other people were ready to gouge me and I was very happy with the work. + he is an actual musician who understands what it is like not to have any money. actually.

Extremely personable and accommodating. Did some work on my acoustic. Plays and sounds better than ever! Gonna take him my other one soon. Great prices and quick turnaround.

This will be your go to for all of your instrument repairs as it is mine!

Friendly, knowledgeable, and great to talk to. Made a quick repair on my Jazz bass while I waited. Though it isnt the norm, he made and exception and really made my day. I would definitely recommend. Great above and beyond customer service.

Justin Has Worked On Several Of My Guitars, His Work Is Outstanding. Great Guy As Well!

Justin did an excellent job tuning up my telecaster. He even correctly deduced what style of music I play based upon the wear of the guitar and the nature of the issue I was having. When other places had a 2-week turnaround and wanted to charge twice as much, Justin had mine ready in 2 days for a very reasonable price. Plus he knows the metal scene and is just a friendly guy. Whereas before I broke a string a week, now Ive been on the same set for a month with no issues, and I play hard. Ill definitely be hitting Justin up on the reg for future tune-ups.

Justin worked on some guitars for me. Not many people want to mess with a Floyd Rose but he did so wonderfully. Highly recommended.

I highly recommend using Justin at Hackl guitars for all your guitar repair needs. He does great work! Dont go to Guitar Center!! Support local business!!

The best guy in town doing the best work. You should absolutely give him your business. 🤙

Crazy quick turn around on my acoustic that hadn’t been worked on in almost 20 years. Amazing service and fair prices.

Justin of, Hackl Guitars, is the absolute best! Fantastic work, timely turnaround and doesnt charge you the price of new guitar to get a little work done. If your in the Denver area dont take your Guitars or Basses to anyone else! Top notch work from a great dude!

Omg this great guy just repaired my bass guitar. great service and in under 20 minutes he got my baby playing!!!! great price for repairs please please support local business like the one JUSTIN have!!! hes simply awesome.

He’s great at what he does and he’s very knowledgeable & helpful. I would completely trust him with anything guitar related.

Great guy. Was able to get my Rickenbacker Bass in and out while I waited. Very reasonable prices!

Justin does great work. His work demonstrates top notch craftsmanship and care at extremely reasonable rates. I will not take my guitars anywhere else as long as Justin is around.

Now, we all know guitars are sensitive to climate and moisture. We also know that the air in Denver is high and dry. So, what happens when we move to town and bring our guitars with us from sea level?They crap out on us. But we know some other things.We know that a good tech can quickly get our guitars ready to play, even if they barely survived the pressure changes in the back of a U-Haul. We also know that the best techs can get our guitars to play better than they ever have before. So, what happens when we bring our guitars to Hackl Guitars?Our guitars rock again.P.S. Basses too!

Justin took my already setup guitar and did some sort of crazy magic to it to make it even more playable with no fret buzzing or tonal tradeoffs. Add to that hes an incredibly nice dude and I cant imagine going to anyone else in the Denver area.

Great set up on my guitar. Plays so much better now, can really feel a difference.

Took my Fender Acoustic and Fender Baritone out to Justin to get work done. I thought the Baritone might be an issue since it is not all that common. Within two days Justin was in touch asking pertinent questions and making sure I knew exactly the work he was going to do. My guitars were ready within the week. Both guitars have never sounded, or played better AND the price he quoted me was the price that I ended up paying. From here on out Justin is the only person in Denver that I will take my guitars to.

Couldn’t ask for a better guitar repair experience. You get to talk directly with the person who fixes your guitar instead of handing it to someone at Guitar Center that doesn’t care, and in return you get someone who takes pride in his craft and works hard to fix your problem. I highly recommend Hackl Guitar Repair Shop.

Finally got my Stratocaster to Justin and it plays better than the day I bought it 12 years ago! Great honest work, great price. Hope to have a custom built with the Hackl name on it soon!

I have been a customer of J. Hackl. For 10 years. Impeccable work! My go tofor bass/guitar repair.

Great shop

Great experience! Im a basement hobbiest, and only semi-know what I am taking about...I was made to feel very welcome and was given what I believe is a very fair price. I was given a simple and inexpensive solution for something I know a box store would have upselled me on...great work at a great price point!

Took in my vintage Les Paul to get tuned up and have the output jack resoldered. Justin finished ahead of quoted time and my guitar sounds amazing. Staying in tune, polished up and the action is phoenominal. Highly recommend.

As an amp repair tech in the Denver area, I have meandered through my fair share of guitar workshops and luthier shops. Hackls devotion, work-ethic, and passion for enhancing the craft for both himself, and for his treasured customers. It shows in clean and precise work in all the guitars he both repairs/restores. Hackl will be the future of artisan guitar work, and thankfully, is the present of it as well.

Have taken several guitars to Hackl for setups and mods. Excellent workmanship and speedy turnaround time. Highly recommended!

Nice work. Guitars set up Well. Friendly and knowledgeable

Justin has worked on two of my guitars so far. One was a routine setup and he did a bang up job. He even went ahead and put in the extra effort to help fix a grounding issue while doing a pickup install.

Fast service at a great price. Justin does great work!

Justin is the man - a one man show with his shop thats out of his home in Park Hill. Not going to add much more thats already been said about his technical ability to setup, tune, repair, or build guitars - hes legit and knows his craft well. But Ill add that he is just a super down to earth, friendly, and a straight shooter. Hell be honest with exactly what your instrument needs and what to focus on versus leading you astray. He has setup/tuned a mexi-Tele for me and just recently helped to re-build a Stratocaster by installing a new neck, new pickups, new pick guards, and installed all new electrical/pots. Both guitars are just perfect now. Hes the guy and Im definitely always bringing my instruments to him to get worked on.

Top notch work, super knowledgeable, friendly service, fast, what more can I say. IN PARTICULAR go to Hackl Guitars if you are looking to get heavy.

Justin is super cool. This is where you want to bring your guitars.

Best dude. Best shop. Best best.

Justin does great work.

Great personal service....Thanks Justin.

Reasonable rates, fast turnaround, great work!

Super fast turnaround, excellent prices and excellent service.

Dude knows what he is doing. My rig plays excellent now!!!

Highly recommend Hackly Guitars!I recently had Justin install a set of pickups for me on a Stratocaster. They had a bit of a strange wiring pattern, due to the S1 switch and the fact the guitar was put together from many different parts. He took the time to research the best way to setup the electronics and perfectly set it up for me. My Strat plays 1000x better after his setup than it did before.Justin is a great guy and a very talented luthier. I highly recommend him for any repairs you may need, especially guitar setups!

Awesome service. Very helpful.

Superrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr Superrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr Superrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
