John has repaired two of my Fender Amplifiers. I found the invoice to be less than expected and the work appeared to be of top quality.He has also repaired three of my guitars. Here the results were better than expected. In each case the tone improved by at least 100% and each guitar was much more playable. He replace a broken nut on a Korean Martin SDR-28 and set the action. It now plays and sounds (to me) better than my Martin HD-28. I’m quite pleased and kind of hoping something happens to cause me to take in my other two guitars he has not worked on yet. I am also considering having him build a custom Telecaster for me.

Every time John sets up one of my guitars for the first time it becomes my favorite. Not because the others have deteriorated but because I’ve struggled with what I had that when setup right it is a joy to play.

I recently brought in my 65 Amps soho for some love as it was not doing well at all. I got it back today and I am super stoked! Not only is it sounding ridiculous again, but they were also able to fix a master volume issue that has plagued the amp since I bought it. Two big fat thumbs up guys!!!

Best guitar/gear repair around. I buy a lot of used and new guitars so I’ve had many guitars over the years
(I swear they’ve become an obsession)and used lots of service techs at various guitar shops, most were good with a few bad ones mixed in but then a fellow guitar guy told me to try JJ guitar and let me just say they have been the best I’ve ever tried, the attention to detail is amazing, they always provides excellent service, and you can really tell the difference in the instrument when finished no matter what the issue is and they can do just about anything to your equipment, they are very skilled in the craft and always do a Wonderful job, I will always take my gear to your shop, definitely the best.

I’m telling all my friends to come here.
Satisfied big time.

John did an awesome job on my Takamine 12 string guitar. John whatever you did on my guitar, it has never sounded better, it was like I was given a brand new guitar! John you get two thumbs up in my book. I will be bringing my other guitars to you for a set up! Thanks!
