Adding Tone Controls to 2-Knob Fuzz Pedals

[debrad]

Super excited...my daughters bought me a pair of breadboards for Christmas so now I can sit down and test a few options without having to commit anything to solder!

OT: i wish i asked for breadboards from Sinterklaas (Dutch Christmas), having more sure is helpful, since i always have multiple projects running.

Just to provide some closure on this one...

I stuck my modified BMP tone control (tone+body) between the Super Fuzz "tone" switch and volume knob but the volume loss was VERY noticeable so I added an LPB-1 boost circuit between the new BMP circuit and the volume knob.  Problem solved.  All the great Super Fuzz tone I was getting without the tone and body pots but now with the added ability to tweak the output tone in addition to the 2 settings of the "tone" switch.

Huge thanks to everyone for all of their feedback and suggestions.  I really appreciate it!

Here's how it all looks:

it looks absolutely great! i love the name as well
i guess it gets SUPER SCOOPED when you have the mode switch in scoop and the body all the way down.
two scoops (of ice cream), which ties in with the name again, haha

My only real complaint (aside from wishing I could tidy up my wiring) is that I couldn't get a really great octave to pop.  I'm not all that familiar with the Super Fuzz or the Danelectro Eisenhower Fuzz but I get the sense that the octave is a little more subtle than the Foxx Tone Machine that I love so much.  Having said that, the RJ Ronquillio Eisenhower demo I watched seemed to showcase a pretty decent octave with certain settings...

Other than that, I am pretty happy with how it all turned out...especially how well the modified BMP tone circuit works and how well it interacts with the stock 2-position tone switch.
