Blend board for multi

[Martan]

Hello all,

I am building a multi that I will probably regret

Its going to have a Machete (overboard fuzz), Corrupter (ring mod), and Sonic reducer (bit crusher). I want to have a global blend knob(s) to keep the dry signal available. I've seen a few boards on THcustoms and guitarpcb but would love suggestions, esp. in light of the fuzz with the blends I've seen having buffers in them.

Thanks,

Marty
