Studio Maintenance Center is Mark Paul. I have been using his equipment repair service for two months now and I cannot put into words how grateful I am to know him. He is a shockingly talented repair technician with an incredible work ethic and intense attention to detail, and I am also blown away by his personal generosity(for one example he personally delivered a repaired mic preamp to my Oakland studio early in the day just in time for an important recording session, and didn’t even ask for money to do that though I did give him some). He is the best repair technician I have encountered in the 15+ years I have worked as a professional recording studio owner/engineer. Any studio which uses vintage equipment needs to know an excellent repair tech, and Mark is probably the best. He is an absolutely phenomenal resource for the Bay Area recording community. I cannot recommend him highly enough.
