For all of our customers in and around DC we have a drop off spot in Upper Marlboro at East Coast Drums. Just head over there and Dave will get you squared away.


For our customers in the Annapolis area, you can drop off your repair at Bay Tunes; Jeff will be happy to get you logged in.


We are also implementing a new automated tracking system to help keep turnaround time down and keep you informed about the status of your repair.

The new facility has space set aside for reconing speakers. We are now a competitive reconer of just about any speaker you can imagine. Also we can take in big repairs such as Hammond organs and whole PA rigs etc.
