How to connect your amp with 4 cables method
The basic principle behind the 4 cable method is to use separatly the
preamp and the amp sections from your guitar amplifier. This is only
possibile if your amp has serial loop effect connection. Once you
separate the preamp from your amp you can place the preamp be-
fore the modulation effects. Make sure that the preamp-send-signal
(normally indicated in your guitar amp as channel volume) is not
too high to saturate/distort the effects in the PedalPro Ex. In practice
just turn on the chorus of the PedalPro Ex with chorus input and wet
to100% and adjust the volume knob on your preamp untill you have
no distortion. Any power loss can be compensated by the Amp gain
knob placed in the back of your unit.
Since you are connecting the ground of your amp with the PedalPro
Ex in multiple points, you may experience HUM due to ground loop. In
this case you need a ground isolator (DI) in between. Contact us to
get a list of recommendable devices.
By default, each preset and Lead sound is set to be used in a
normal amp configuration (page 8) . If you are using the 4 cable
method engage the Ext_effect switch in the preset and in both
Leads (page 10 and 53). By activating the Ext_effect the pre loop
is turned on and the preamp section of your amp is chained in the
PedalPro as shown on pages 64-65
