A/B channel switcher effects loop layout - any problems?

[composition4]

Hi all,

This is my first post here - I have been lurking around for a long time and have learnt a lot from this forum and have now built a number of effects, so first off I'd like to thank you all for making this forum work!

I am currently building a box to switch between an "A" channel and a "B" channel.  I will have 3 effects loops, and switches on each loop to turn on the loop for the "A" channel and/or the "B" channel. It will also have a switch on each channel to let me change the channel on my JCM 800 (2210 model, so it's just a simple tip-to-sleeve connection).

The layout I have devised means that I will need to gang together two 4pdt footswitches (the blue and purple connections). A couple of questions - is my layout okay? I understand that the inputs/outputs to the individual effects (the dpdt switches in red and yellow) will not be grounded when bypassed, but I don't think this will be a problem?

Also, is there an easier way for me to do this? i.e. with only one 4pdt or anything else? I know that relays or switching ICs would be ideal here, but would like to stay with mechanical switches for this one due to my lack of experience with relays - I know that it's no excuse!

Please ignore the part highlighted in green (the last two sets of pole on second 4pdt, I have that bit figured out - it's for the LEDs and amp switching). I hope my layout is clear enough to understand...

Thanks in advance!

I noticed there's quite a few views but no response - I have a feeling that I didn't make my post very easy to understand. Was kind of late here when I posted sorry!

Basically the lugs in blue and purple are two 4PDT footswitches which I will mechanically join together, so that they both switch at the same time.  The three FX Loops FX1, FX2 and FX3 will each have a switch on them (the DPDTs in red and yellow) so that the loops can be turned on/off for the A channel or the B channel.

My questions are:

1. Does this layout work?
2. Is there a better way to do this with switches (sorry I don't have the knowledge and time to work with relays at this moment - wish I did)

Hope it's a little more logical this time... thanks!
