This is a great-looking Tremolux head from the blackface era, featuring FEIC badging on the front and back. The Tremolux is essentially the head version of a Vibrolux, but without reverb. These are widely regarded as sleepers within the blackface lineup, as they cost about half the price of a Vibrolux Reverb combo! Internally, the power cord and electrolytic caps have been replaced. The original speakers have been changed out for Eminence Legend 1058, which sound great. Fortunately, the amp has retained all of its original preamp resistors, along with the coveted "blue molded" Ajax coupling caps, ensuring the blackface sound remains intact!
