What We Do
Swantronics specializes in vintage tube amp repair and servicing. Currently, I do not work on solid state amps, guitar pedals, or pro-audio gear. I’ll always be upfront with you when the work is out of our wheelhouse.
What to Expect
When any amp first arrives in the shop, it’s serviced before starting on any other repairs. This service is recommended annually, especially on frequently played vintage amps. Many times, a good servicing is all the amp will need. If any other repair is needed, I’ll provide an estimate for the additional work. No work is done beyond basic service until it is approved by the customer. Turnaround time varies depending on the current workload. If you’re in need of rush work, please email me. I try to leave space for touring and working musicians that use their amps to earn a living.
