ENGLISH REAR PANEL FUNCTIONS The Dual Reverb range was designed for versatility with two independently controlled footswitchable channels, each voiced totally differently. Channel A is voiced for brilliant clean tones with the gain control (item 2) on lower settings and crunch to lower gain lead as you turn it up. Channel B is boosted with enough gain (item 3), for fearsome lead tones, ranging from classic on lower settings to contemporary screaming solos on maximum.
