So for anyone reading this.
I re-jigged the connections around so that the Stomp goes before the switcher instead of the other way round still using the above connections respectively and it works very well! I had to
adjust the effects loop so either a "send or a return" instead of "FX loop L" as I found that when using the on board preamps, some of the signal seemed to be routed through the clean
channel of my amp which was weird instead of the amps FX loop return.
I now consider the 7 cable method or whatever it is conquered!
