Whats up every. I think ive stated before that ive only been modding pedals for about 6 to 8 months and recently aquired a v1 barber trifecta. The 3 way vocing switch and ive already clipped the 15k resistor barber recommened to get a little more variety out of the voicing switch.

I would however like to add a separate mini on on on 3 way toggle in conjuction with the 3 way voicing switch for 9 total variations to play around with. Any ideads on how i would do this fellas? Is a 3way on on on mini toggle the proper toggle i would need and how would i wire it it?

I can read schematics enough to get myself confused so dummy terms with diagrams would be best for me. I asked mr barber yesterday about which transistors he used in the pedal (because i was out of town and didnt have it with me) and got a very rude answer asking me if i knew how to read because theryre marked on the trannies. So i would prefer to avoid him and just ask you guys since everyone has been so nice and helpful so far

Thanks everyone

It's a modified Big Muff, the transistors are 2N5088. I'm not sure how the sludge control works, but from the description in the manual and gutshots posted over at the other place it appears to be a simple high pass filter/bass roll-off on the input. I thought the voice switch altered the tonestack, but again from the description:

Quote"Toggle allows you to select between three classic fuzz circuits. The Left Toggle is the
vintage "Triangle pi" style sound. Center is the Jumbo Bender type sound. Right is the
Suppa Bender style sound"

... and gutshots, it maybe removes a pair of clipping diodes (for Jumbo bender), and maybe does that and a further tweak to get the "suppa bender" sound.

Another toggle could be used to alter the tonestack for midscoop/flat/midboost: Big Muff tonestack mods are all over the net.

Better still, plan and build your own BMP with whatever mods you fancy. It would probably be easier than risking performing a mod you don't like, or risking damaging the pcb when de/soldering.
