How would you wire this switch?

A wired from the pcb to switch with another from the pot to the switch?

LIke all other BMPi variants with added mids switch.. :icon_wink:

edit: The above switch is a Tone bypass one but you get the idea..

I made my own. Here's a blog post I wrote about my build: http://www.super-freq.com/watas-electro-sound-big-muff/

I used NPN transistors instead of PNP. EQD did the same thing in Hizumitas. I found some NPN devices in what I think is the same gain range as the PNP devices used in the Elk Super Fuzz Sustainer.

I used 100k pots. EQD used a 50k pot for sustain or volume.

I don't think these choices matter as much as the resistor and cap values for this circuit.

I appreciate the response. But I guess since I'm not working from the schematic its hard to wrap my head around.

There is an output from the pcb to the 3rd lug of the tone pot.
There is an output from the PCB to "SW1".

There is and input on one side of the Switch for "Tone 3" and another for "SW1".

My confusion is how do i wire theswitch to work? it kind of makes no sense to me, even looking at the schematic.

Nets with the same name are connected. Yes, that means "Tone 3" goes to both the switch and the tone pot's 3rd pin. Note that the switch is a DP3T on-off-on type.
