With the exception of the IC BMP (’77, ’78) you can theoretically build just about any version of the Big Muff on any other version’s layouts, but the values listed in this one are for the Tall Font Green Russian version. This one is smaller than the BMP layout I did with on board pots and you should be able to fit it in a 1590B if you shave down the sides of the board a little.
One of the better sounding versions of the Big Muff (IMHO anyway) and sounds great on both guitar and bass.
And if you want to cut through the mix a little better, here’s the Green Russian with a modified tone stack, adding a mids control. Pinkjimiphoton over on FSB suggests using a higher value pot for the mids control (250k-1M) than the normal 100k that’s listed.
Update 3/16/15:
Modeffected pointed out that these 2 layouts were missing the 12k resistor from the power rail to the collector of Q3. Both layouts have been updated and should be correct now.
