They are fast (as possible, of course) reliable and pro.They are also little cheaper than the competition and the service is the same (if not better).They are also a go to repair for some music retail stores.

Jon always has been super helpful and super quick with all of my repairs. Guitar amps, synthesizers, pedals... you name it, Jon will repair it. Appreciate greatly having an alternative to Deltronics who are generally far backed up. Thank you Jon!!

Jon repaired my Moog Grandmother and Mother 32, and I am very grateful. Cant make electronic music without experts like Jon to repair/make/maintain the instruments.

After another Chicago-area repair shop (Ill do them a big favor by not mentioning their name today) tried to con me into believing that my new Tascam Portastudio recorder was beyond repair (I suppose so I would believe him, and save myself their $40.00 analysis fee by just letting them keep the thing), a manager at the Evanston Guitar Center recommended Outlier Audio (who they use for repairs like mine).Jon was as courteous, prompt, honest and as professional as any customer could hope for, and easily repaired my issue in one day at a very fair price. Just picked it up today and man, am I happy.....Thanks, Jon. See you again, somewhere down the road.....

Total Scammer - Tries to look like a big shot at the expense of other people. Will rip you off at every chance! DO NOT TRUST THIS SCAMMING IDIOT!

Jon is amazing! He was able to repair a Roland board for my digital keyboard that had some liquid damage. Works like a charm. Highly recommend.

We use Jon and his services for our music shop in South Bend, Indiana and its worth the drive knowing we get top notch service. Outlier goes above and beyond. Highly recommend.

The only place for professional service on professional stuff that plugs in the wall. Jon Rocks!

Compelled by the awesomeness of this place to write my first Google Review. Jon/Outlier is amazing!! Totally reasonable rates, great work, great turnaround time.

Jon got my hifi monitoring system sounding better than ever! He knows his stuff!

Jon repaired an old receiver for me that I was ready to give up on. I was surprised how knowledgeable he is about all kinds of audio equipment. Very professional service and trustworthy.

Fixed an old tape echo of mine for a great price. Excellent service and communication here, highly recommended!

The tech really knows his stuff! I broke the pitch bender on my keyboard and was ready to give up. Jon not only showed me how he fixed it, but how he had reinforced it so I wouldnt have the same issue again.

Jon (formerly of Deltronics) is the absolute go-to guy when any of my gear breaks down. The best!
