A/B Looper Design

[Visualdistortion]

Hi, I need to switch between 2 pedals during my set (like a fuzz for rhythm and one for chorus/lead) and I prefer switch between the 2 with only one switch and shut them off with an other switch for get my clean signal.

I "designed" this layout but I don't know if I did right, or maybe there is some improvement to add. I don't put the resistances for LED.
Also is it possible to add an extra switch:
- to put loop A on B or B on A?
- to put A and B in parrallel? (like this one: http://www.brightonion.co.uk/aby-dual-looper/)
Thanks

That schematic will do want you want it to do.

On the other questions, you could botch a simple "parallel" switch with a DPST or DPDT toggle switch, just use one pole to connect/disconnect "send A" and "send B" and the other pole to connect/disconnect "return A" and "return B". You might want to use a buffer before the "input" and maybe mixer resistors, it will depend on which pedals you have in the two loops and how/whether they interact unfavourably when parallel'ed.

The "series" (A->B or B->A) might be a bit more involved. I'll have a think about it.
