What We Do

Swantronics specializes in tube amp repair and servicing with a specialization in vintage amps. .We do not currently take on solid state amps, guitar pedals, or pro-audio gear. We’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, we’ll generate an estimate for the additional work and the first half hour of labor will be credited for that work. No work is done beyond basic service until it is approved by the customer. Turnaround time varies depending on the current workload.

Standard Amp Service

Standard amp service includes:

• testing all tubes

• cleaning pots, jacks, etc.
