Civil War Muff/ToneBender hybrid

Ok, here's the plan:
I want to build a pedal that has a sound somewhere between the Russian/Civil War/etc... Big Muff & a ColorSound Jumbo ToneBender.  I am going to use a ready to solder PCB from General Guitar Gadgets.  I can't decide if I should get a BMP circuit board, install the component values of the Civil War, but use the BC184C transistors from the ToneBender & add a toggle to lift the second set of diodes, or if I should get the TB circuit board & install the component values of the Civil War. 

I guess the reason I'm asking a question is because if I use the Muff PCB, it has a spot for the 4th transistor.  I'm not savvy enough yet to be confident that I'll know how to troubleshoot the build if not installing the 4th transistor causes a problem.  Then again, if I use the TB board, I don't have the second set of diodes option.  That may or may not really matter, but I'd like a 2nd (& 3rd, 4th, 5th) opinion from some of you.

If you're curious, I'm using it for bass.

i would breadboard it instead and test to see if you like it.....much better for tweaking/options..just my 2p... ..

If you want the option of diodes/no diodes, you need that 4th transistor. Rick Holt did a nice perf layout for a Big Muff with an extra pot as variable resistor in series with the first set of diodes so the exact amount of clipping could be dialled in, basically a JumboTB/Big Muff blend control. Might work really well on bass.

Thanks for the help guys. I think I'll go Muff PCB, Civil War component values. I'll use BC184C transistors & 1N914 diodes in both pair, but I think I'll put the second set on a DPDT on/on switch to add a germanium option. Probably use a 1N34A pair. Should I do both diode pairs that way? Maybe I could even add a JFET in the 4th transistor stage. I've heard that can be pretty cool.  Or maybe not. This is already getting to be option heavy for just a bass fuzz.

I'll probably install a tone bypass switch too. Seems easy enough.
