Mike Metz is a wizard. I recommend him to many people. You have something needing repaired or tuned up, boards, amps, guitars, keyboards new or old, Mike Metz is your man. Been working on my gear since 1985. Only one that touches my stuff.

Super friendly, honest work, and great prices on repairs. Been going here for years

Mike is great.

Mike is by far the only person I will allow to work on my gear. He does exceptional work, always upfront and honest about the work to be performed, and if he cannot fix it, throw it out (or he’ll tell you to chuck it!). From amp re-tubing to guitar set ups to instrument restoration, Mike does it all. I recommend him to everyone.

Mike Metz has been repairing amps, electronics, guitars and many other things music related for the last 20 years for myself and many more years than that for everyone else. Everyone in town knows who he is and hes one of the nicest and smartest people I know. I sure wouldnt trust my instruments to the darkness of guitar center but I sure would trust all my gear with Thesis Audio.

Mike at Thesis Audio Service has been repairing my gear and building custom pieces for me for over forty years now. His work is nothing short of Artwork. Incredible attention to detail and Mike has always gone above and beyond to accommodate even the craziest of my requests. He kept my elaborate rig in tip-top condition through all my touring years. Now, In an era of lackluster service and shoddy workmanship, Mike remains a true craftsman and a man of great character. Thank you for everything, Mr. Metz!

He does all of my maintenance and repairs. Great job!

Best place in town. Always upfront about what needs to be done. Never once steered me wrong! Been coming here since I was a teenager!

I have known Mike for decades. He is the ONLY person who touches my Ampeg SVT amplifiers. He does excellent work and is extremely reasonable with his pricing. Mike does work for some of the biggest names in the business as well. Theres a reason for that. Theres nobody better! I highly recommend Mike for anything related to amps, guitars, and keyboards, including full on restorations. Thanks Mike for the MANY decades of excellent service!!

Mike is a solid guy and very open and nice. I listed two stars because I dropped my amp off (I live almost two hours out of town) to have it repaired. After giving him the time he needed to repair it, I returned to pick it up. When I went to try it out, within five minutes of use, it was having very noticeable issues similar to the issues before the repair. I called him to see what he may think it may be, hoping it was a bad tube, but he wasn’t sure without looking at it, which was a total bummer because I didn’t want to make another long journey to have it fixed. If I lived closer, it wouldn’t be too big of a deal, but I was very disappointed and felt I wasted my time and money.

For the last 6+ years, Mike has set up all my basses, and has repaired an amp. Hes honest. Answers any and all of my questions. He does a great job, its usually a quick turnaround and more than fair pricing. Mikes the one for my guitar and electronic needs.

Mike has worked on my gear for years now and Ill never take it anywhere else!

Mike is a genius in his field. Always completely honest with you about what your gear needs to be top notch.

Mike resurrected two of my favorite amplifiers from the dead. They both sound great and ready to jam again.

Known Mike for decades (Do-Da music scene). Worked on so much stuff. Last was a Kahler on my Koa Explorer bass. Awesome. Attention to detail, expertise, and user friendly. Working on my Ashdown Bass Head next. Only man I trust. If you read this, Mike, thanks, you are rare

Mike is a cool dude and knows what hes talking about. Take all your amps here!

Mike is down-to-earth, knowledgeable, quick, fair, and does quality work, let alone the fact that hes brand-authorized to work on pretty much every make of keyboard around.

Best place in Kansas to get your amps, pedals, etc.. repaired. Mike is the best.

Very helpful, I was fairly new to guitar and didn’t know what was wrong with my amp and he helped me find out what was wrong and fixed it.I will always recommend him.

Cool dude who knows what hes talking about. I go to him for all my amp repairs and services.

100% best service in town!

Mike has always got my gear going in the blink of an eye. Long time customer.

Not really willing to help

Nice
