well..  the most usefull thing to do is getting an A/B switch imo.. 
i like the EF86 side with it's volume at about 40% (prepare your ear-pluggs), tone switch in 2nd or 3rd position.
'TB' side - 50% vol, bass on ~25-30%, treble on 50%..
guitar goes clean to the clean channel..  through a fulltone OCD to the EF86 - bliss...

have fun

Hi,
i'd like to make me a wiring/switching box which will allow using 1 effects chain for both of the channel's effects loops..
my idea would involve 2 stereo jacks(with normal stereo cables plugged into both effects loop jacks on the amp) and 2 mono jacks - send & return for the chain.
i don't really know how to wire this thing..  any ideas ?
plus, if there's a way (probably would involve more parts)i can have a common chain and a seperate chain for each channel, that can be nice..

thanks
