A built-in Guitar Preamp.
I N S E R T C A R T R I D G E
The Z-DSP contains a simple monophonic Guitar
preamp that can be enabled by 2 jumpers at the back
of the unit.
The first jumper allows a choice between synth (line)
level and guitar level.
The second jumper enables the preamp for both
inputs, or just the Left input.
In any case, a guitar should be connected to the Left
channel input only and let the second jumper control
the routing to the Right input.
