The INSTRUMENT OUTPUT (32) delivers a signal similar to the one generated by a guitar's
pickups when the preamp is active (PREAMP DEFEAT switch Off), i.e. a high-ohm signal at about
the same level as a guitar signal. This feature is relevant when you want to establish the
same conditions via a bypass circuit (guitar signal to the INSTRUMENT OUTPUT) for further
signal processing, for instance by an FX device, another Preamp connected in series or a
poweramp.You can connect a signal processor between the INSTRUMENT OUTPUT (32) and
the FX LOOP RETURN jacks (30) and (31) or directly between the LINE OUTPUTS (27) and
(28) and a stereo poweramp's inputs. There is a substantial difference between these two
applications:
When you connect the Processor to the FX LOOP, the send signal is identical to the guitar
signal when the preamp is in defeat mode and the preamp signal when the defeat mode
is off. The send level only is influenced by the settings of the volume controls in this case.
The level of the master output signal routed to the LINE outputs can be increased via the
LINE LEVEL (29) pot.
However, when you connect the Processor between the LINE outputs and the poweramp,
the input (Send) signal to the FX device can be increased via the LINE LEVEL (29) pot and you
have two Send signals (left, right) available. This option is recommended for low impedance (0 dB)
FX devices that are not equipped with a variable input.
