Ciaran, I don't have a schematic. I was just wondering if anyone may have added one. Honestly, I wanted to add one just to use an old enclosure that was drilled for four pot holes.
Silver Blues, that is similar to what the Black Arts Pharaoh uses, no?
personally i don't like any of the mids pots i've used on a lot of the modded muffs, but the mids switch i fee does wonders. i was thinking, why not do a cap blend in place of the venerable mids switch.
I'm using a switch now and it does work very well but I thought I'd like to have a little more control over it, like in the LSTR. I haven't been building too much lately so I was looking for something little to do and get back into it. I tried adding a cap blend to a Fuzz Face and it didn't work out to well but I thought it worked great in the Doomidrive.
if you're happy with the mid pot of the LSTR, which is a muff variant like the pharaoh, why not look at the schematic and make the changes to the russian green muff? i've got a real pharaoh, and while it's nice, i find the mids pot to be less useful/impactful as the mids switch. which is why i prefer the mids switch.
silver - i'm sure it's not a new idea, but i tend to have some good ones every now and again. travis has heard so many that usually start off with "i have a stupid idea, what do you think about....." usually he tells me they're great, but i never do anything about them. so many circuit ideas i should actually work on that never do. one day.... lol
pasted some tone stacks from KitRae's site. I was going to also recommend the Supercollider if you like the Green Russian with more control. If you want to mod an existing pedal, then a mid switch that makes the scoop a little less drastic, yet not fully flat is a good way to go.
