The external effects may be connected between both preamps (CLEAN and LEAD) and the
MASTER section through the parallel EFFECT LOOP.This type of connection is recommended
when the Volume pedal or Delay, Reverb, Flanger type of effects are used.IMPORTANT: The
volume potentiometers in both channels determinate the amount of gain sent to the effects.
If too much signal is sent to the effect, unwilling distortion can occur. In which case the
Volume potentiometers should be gradually lowered. Subsequently, the sound level should
be equalized by increasing the volume by MASTER potentiometer. When the mixer or the
external amplifier is connected, the LINE−OUTPUT with integrated cabinet simulator must be
used. Such would simulate the sound of a 412 Celestion Vintage 30 Cabinet. The cabinet
simulator enhances the sound that is sent to the stage monitors as though it were coming
from a stage cabinet.
