Hello all...

New to the forum, and have been learning alot off of all of the excellent posts and info on the site...Thanks everybody!!!  Here is my dillema, and I hope someone out there can help...

I am building a bypass looper and amp footswitch box.  I have 2 separate loops on the box, one for in front the amp, and one for in the effects loop.  The in-front-of-amp loop has two bypass loops, one for my comp, one for my BB preamp, which then feeds into the input on an M13.The third separate loop, has my Boost which goes into the M13 loop, out to the loops/amp input, etc. (4 cable method).
All the loops work, LED'S and all, and I have a very clean signal, no buffer either.  My issue is wiring up the footswitch.

The amp is a modded Bugera V22.  According to the few schematics that I have been able to find on-line, the switch is a latching type footswitch, but is a TRS...channel select and reverb in one plug. I have an isolated mono jack installed for the footswitch input.  I can get the amp to switch channels, but it takes two steps to flip channels.  I have tested the footswitch jack, and with a plug in the amp side jack, and me grounding the tip on the bypass box, I can get it to change channels in one click.  Once I plug that bad boy in, it takes two...Does this mean it is instead a momentary switch with relays?  Or could it be the mono jack?  I have plugged it into a 1/4 inch jack Y splitter (male TRS plug---> 2 female jacks) But still the same thing.  I am also adding in an LED for channel indicator.  Which, by the way, my amp sends about 7V down the wire to power the LED. 

Also, I would like to flip loops 1 & 2 along with changing channels on my amp.  When set to clean channel, I have the comp in the loop.  When switched to gain, I have the BB in the loop.  I have found a few schematics, and I have tried all kinds of combinations, but with no luck at all. 

I know it can be done, as I have seen a few on-line.  And I have read up so much about 3PDT switches and getting to understand them, but I just can't get it to go the way I want it to.  So, I humbly ask for anyone's assistance in this one of the 4 projects I got going on right now with my gear!!!  I kinda got the other three under control...it's this one that is being a bitch!!!  Any advice, diagrams, schematics, if a 4PDT would work instead, whatever, would be so greatly appreciated!  Thanks in advance to anyone who is willing to help a brother out!!!  :icon_biggrin:
