Jack Socket - For 2-Way Footswitch (Preamp1/2, Boost on/off)
This is a stereo 1/4" jack socket for connection to the supplied two way latching
footswitch, that enables the user to footswitch between preamp 1 and 2, and to operate
the BOOST function remotely.
This can be used as well as the optional five way foot controller if desired, however, due
to the 2 way footswitch being a latching type, when switched on it will take priority over
any other switch.
Effects Loop
This has sockets for SEND and RETURN and a level for each, as well as a switch for
SERIES or PARALLEL configuration.
Send, Level
The SEND socket is for connection to the input of effects units. By correctly adjusting the
LEVEL control, this can drive floor type battery powered effects pedals or 19" rack type
studio effects units.
The actual setting of the LEVEL control will depend on several things:- the output of the
guitar, the preamp settings and the level needed to drive the particular effects unit.
The general idea is to set the level as high as possible, (which improves signal/noise ratio)
without creating distortion.
As a guide, if floor type pedals are used the LEVEL will probably need to be set
somewhere between '0' and '5', whereas if studio rack type devices are used it can be set
higher up so that the level indicators on the effects unit reach their maximum point
during peaks in the playing.
Return, Level
The RETURN socket is for connection to the output of effects units. The function of the
LEVEL will depend on whether the loop is set to SERIES or PARALLEL configuration.
In PARALLEL operation the LEVEL control will set the amount of effect signal mixed in
with the straight, un-effected 'dry' signal when the effects loop is switched in, it has no
effect on the dry signal.
In SERIES operation the LEVEL control will set the overall level of the total signal (sent
from the effects unit) when the effects loop is switched in.
Unless otherwise desired, it is best to set this so that when switching the effects loop on
of off there are no great leaps in volume difference.
Series/Parallel Switch
The SERIES/PARALLEL switch alters the configuration of the effects loop.
In SERIES mode the whole signal comes out of the amp, into the effects unit and then
back into the amp, where as in PARALLEL mode the effected signal is mixed in with
8
the original dry signal, thus ensuring tonal purity of the dry signal.
