Adam Kachersky apprenticed for legendary amp tech Dennis Kager for 12yrs, specifically chosen by Dennis to ensure the same quality service Dennis delivered for over 50yrs would continue flawlessly into a new generation and for many years to come.


Dennis’ vast knowledge of vintage amps but especially AMPEGS, the company he joined in 1963, was a cornerstone of the repair business for decades and thankfully is our specialty here at Generation Electric as Adam continues this legacy. Ampeg amps are not made like other amps and most techs try to fix them like they are fixing a Fender... that is a mistake! If a tech does not understand the differences between Ampeg and Fender amps, he will probably cause more problems. We proudly have one of the most in-depth, knowledgeable and experienced shops dedicated to vintage amps in the business.


During Adam’s tenure at CJMS, the shop served as an official service center for over a dozen companies including serving as Fender’s “EAST COAST REGIONAL SERVICE CENTER” for many years, which meant it was the top tier service center for the eastern United States, not only for Fender customers and endorsed artists in and out of warranty, but also for other service centers should they not be capable of repairing a unit. So in short; they served as a service center to service centers, only second to Fender on the west coast.


CJMS also served as a long time service center for Mesa, Marshall, Ampeg, Peavey, Crate, Roland, Korg, etc.. Adam gained 12 years of first hand experience while apprenticing for Dennis Kager at CJMS, working on all types of gear and brands, from the dawn of vintage amps to the most modern equipment. Adam has repaired gear for Artists including Bob Dylan, The Rolling Stones, Mark Knopfler, Sonic Youth, Thursday, Bruce Springsteen, Avril Lavigne, Blue Man Group, Bobby Bandiera, Billy Joel’s Band, etc..


At this time Generation Electric is proud to be an independent service center, not held to any outdated service center requirements and will proudly work on your vintage and out of warranty gear! If you suspect you may be in warranty, please visit your manufacturers website for warranty/service details.


When it comes to quality repairs and proven experience, consider Generation Electric the last place you’ll ever need to bring your gear! Backed by our no-hassle 90 day warranty on our work and parts!
