Splitter Questions

[cps]

Hi,

I'm giving my guitar pedalboard an overhaul and I've got a couple of questions about splitters. I have a little knowledge of electronics (enough to get me into trouble!).

I'd like to have a go at making the runoffgroove Splitter-Blend however I'd like to modify the design so that it has four loops (rather than two).

To make the Splitter-Blend into a four-loop unit, is it OK to simply duplicate the existing circuit?

Also, I'd like the four loops to be independent (i.e. only one is active at a time) so I don't need the final Blend control - can this be omitted?

Finally (and this is what I really need some help with), I'd like to have the four loops foot-switchable so that only one is active at a time using four separate foot-switches. What's the best way to do this?

Cheers,

Chris
