SIGNALS TO THE EFX BOARD
SIGNALS FROM THE EFX BOARD
This shows the effect of the footswitch and EFX
Mute (BYPASS) switch SW5. The FLAG signal goes
off to the EFX board DSP IC U2. The FXMUTE signal
will mute the EFX analog outputs, see below.
This shows the two analog output signals
coming from the EFX board, ready to take
their place in society. The CLIP light will turn
on if the EFX Drive Level is set too high.
This section of the schematic
shows the single analog signal
going into the EFX circuit
board. It also shows the EFX
Drive Level pot R429.
