John has set up two of my guitars and did a pickup swap on my Les Paul. The turnaround, pricing, and transparency of the whole process was amazing! Can’t wait to have him set up my next guitar.

Thank you for upgrading my tele with new pickups and a stellar setup!
The new guy is a keeper!

in this age of very few GOOD techs left that you could find to do a great Job on your amp or guitar John is the only guy to go to and worth it. PERIOD!!! his knowledge and expertise will get you back on stage with confidence that you don’t have to worry about your gear failing and you can get back to what you do best, because he does his very best.

I brought in my Mayones Jabba V custom in to have it set up and have a new preamp installed. I don’t know what voodoo magic John did to my bass, but has NEVER felt or sounded so good. Fantastic work, superb customer service, quick turnaround. Don’t waste your time or money with another shop. Get your work done at JJ guitar repair.

I have had John working on my instruments for a couple decades down and most recently on couple of my favorites used on the road and in the studio. John always has a creative resolve or solid solution or a method of getting things done for and does it at a pretty reasonable rate too. A professional for world renowned musicians and a professional for local area musicians and Pros alike. Super happy with John Jensen and J J Guitars.

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!
