The Twin Reverb II is a 1980s Fender redesign of the Twin Reverb, rated at 105 watts from four 6L6GCs. Channel 1 is the clean side with volume, treble, bass, mid, a bright switch and a mid boost; Channel 2 adds gain and master volume with its own treble, bass and mid for overdrive, selected by footswitch. It keeps 12AT7-driven spring reverb and adds a presence control and an effects loop with send and return levels, ahead of a 12AT7 long-tail inverter.
