Crystalline, versatile and packed to the gills with punch, the vintage Fender Twin Reverb Silverface is an affordable, occasionally overlooked  amp. With hefty 6L6 tubes to fill out even the biggest stages. The Twin's dual Normal/Vibrato channel design is outfitted with three-band EQs and Bright switches for compensation at higher volumes on each side and controls for speed/intensity/reverb for lush tone on tap. Stacked with headroom, it can handle the nastiest dirt boxes with the Master volume knob (unique to the Silverface) barely past noon. Amp checked and restored ! Perfect again !
