There are many great guitar amplifiers out there. At our shop, Schroeder Guitar Repair, the amps coming in range from found-on-the-side-of-the-road freebies that don’t have a heartbeat to boutique amps worth five figures. Many of these amps are old. Vintage amps, like any other piece of vintage equipment, often need updating to function safely and properly. This early ‘60s blonde Fender Band-Master is just such an amp—beautiful, glorious tone, but in need of some maintenance to fully appreciate what the amp is capable of.
