Organized, honest and affordable. Fixed what others couldnt. Thanks

The caliber of work done here is second to none. I have had two vintage amps serviced by Yontz and highly recommend placing your trust and confidence in this business. His value of knowledge and expertise far exceeds the cost of repair. I received clear and concise communication throughout the repair process. It is worth the wait and the drive if you are outside of the Raleigh area.

If you want one of the best amp techs to take care of your gear, then come see Yontz!Yontz put new life back into my trusty fender vibro king. Great work and super good communication thruout the process.

We are incredibly lucky to have Yontz and Mad Science works here in Raleigh. He is a true master of his craft and he does impeccable work. Ive taken several amps in for repair/maintenance and each one has been returned in flawless working order. Scheduling can be a little tricky due to the backlog its a testament to just how good he is. If you want the job done right Mad Science is the place to go and it is well worth the wait!

Amp sounds great! I highly recommend.

This place is 100% worth the wait. Not sure it’s that way all year around, but Yontz was booked 8 weeks out when initially contacted. I had another tech in the area service my ‘78 Deluxe Reverb 3-4 times & wasn’t able to solve the intermittent issue. Yontz had it for a day, found the issues & gave it back - it’s been perfect ever since. Cool shop, highly skilled, great communication & easy to work with. Highly recommended

Yontz is the man.Took him my vintage Crate amp expecting to pay a fortune to have it fixxed.Not only did he fix it but he fixxed it far cheaper than expected.My amp sounds better than ever thanks to Yontz.I would recommend him to anyone.The wait can be weeks but it is worth it.

Yontz is great to work with and knowledgeable. They were responsive in communication. The price for service seemed fair. I felt like they gave me several options and let me choose what I felt was appropriate. I would use them if I ever need an amp repaired again.

I heard about Mad Science Works from my friends a Guru Guitars and went to Yontz for some repair work on my Vox AC15 when the vibrato circuit began to fail. The amp worked perfectly after his repair and I experienced him to be very knowledgeable, efficient AND super clear in terms of communication about repair timelines and cost estimates. No surprises. Fast repairs. Mad Science Works is my #1 go-to for amp repairs.

Very knowledgeable. Gave expert advice on a potential mod and, ultimately, helped me make a better decision about my amp.

Yontz has worked on several amps for me. The price is fair, and he is very good at what he does. Strongly recommend.

I took my Mesa Boogie to get fixed a couple years back and its still working great Im leaving this review because I had to look up his website again because Im bringing another amp to him.

Yontz is the best! I highly recommend him.

Yontz provides a great service, is honest, fair and easy to deal with. I highly recommend Mad Science for all amp repair.

I just had Yontz at Mad Science repair my Mesa amp. This is the first repair shop I have used that doesnt have helpers trying to do the work. Yontz is a genius at electronics and has a background in networking tech, very smart guy. He went over every detail with me and got the latest updates from the Mesa factory, he is an authorized warranty repair for Mesa and other brands. I dont think you would find anyone outside the Mesa factory that could even come close. Highly recommended.

Go support Yontz at Mad Science Works. He does good work and knows what he is doing.

If you have an amp he works on, you will not likey find a better person to deal with. Five star service, this man knows his trade.

Great place to have mods and repairs done to guitar amps.

I have been a customer with Yontz since he first opened his business. His quality of work and attention to detail is impeccable for any kind of thru-hole repairs and restoration involving guitar/bass/power amplification as well as old analog synths. He has also repaired and upgraded my vintage rack guitar switching systems with great results. In my opinion and 15 years of experience with him there is no better musical repair tech in Raleigh than Yontz. Highly recommended.

Yontz @ Mad Science Works has repaired a few of my amps and I cant say enough about the quality of his work. Yontz is passionate about his work and he understands musicians are always working within a tight budget so he gives the highest quality of work that any musician, professional or amateur can afford . I cant see myself ever using anyone else to fix my equipment.Thanks Yontz

Got my ancient Danelctro 15 watt amp back and this thing now rocks!!!he rebuilt two Macintosh tube MC30 power amps previously and they were perfect...thx Yontz!

Great service with these experts. A little hard to find.

Took my 5150 in and got back an animal! Great work indeed!

Because Yontz is the man

Awesome service!
