Footswitch:
Channel Select - selects active preamp channel in mono
mode
Siereo/Mono - selects Mono lone preamp teeoing both
power amps) or Stereo (each preamp feeding its own
power amp)
Cnorus/Vtbraio - Activates the Chorus/Vitxato.
NOTE: When Chorus/Vibrato is active, any selected
preamp signals are ted to Power Amp 1 and the
Chorus/Vibrato signal is fed to Power Amp 2.
Reverb - Defeats the Reverb
Due to our elforts for constant improvement, features and specifications are subject to change without notice.
