Hi, A friend of mine has been offered this (supposedly) bass head from a company called F.B.T. Electronics... We've searched and turned up nothing on them, so were wondering if someone out there knows of them or their equipment. this amp is "Mod. 500 BR-2", seems to be late 60's, and made in Italy. It has Low and High inputs, Bass, Volume, Trebble, Depth and Pilot controls. anyone know anything about it?
