As a return customer to Audio 3000, I knew that Dennis would be able to solve the problems that I was having with my recently purchased guitar amplifier, a used Engl Screamer Head. Immediately, Dennis was able to diagnose that there was something “not right” with it. Much was wrong with the amp. Some capacitors were bad, the input jack was messed up and more. Dennis was able to bring the amp totally back to life at a reasonable cost and in a short amount of time. Now it sounds exactly like it should. The tone is amazing, and better than ever! Like many guitar players, I spend so much time trying to tweak and find that perfect tone. In reality, our dissatisfaction with how we sound can be linked to degraded or faulty equipment that just needs some care. Dennis is the only person I’d recommend and trust with my gear. Thank you Dennis!
