hi, i would like to know how to increase the mids in the big muff from general guitar gadgets, i think mine will get lost on the mix, thanks.

you wouldn't necessarily need the "body" pot, but you could use the examples to come up with a fixed resistor value to accentuate the mids.

the Duncan Tone Stack Calculator would be helpful here too:

  You can diddle with the tonestack, that's where I'd start.
  *Increasing the mids presence [sort of a misnomer]= *cutting lows and highs then turning it up to adjust for the losses.
  *Caps shunting highs [signal path to ground {thru resistor?}] ..*made bigger shunt more highs.
  Caps rolling off lows [series in signal path] made smaller limit more low frequencies.
  The only thing left is whats inbetween...mids.
  Yupp...I'd read all through AMZ labs notebook... :icon_idea: for a time 'er two.

One of the 70s BMPs had a tone bypass switch that made the pedal sound much better.  I believe that if you insert a switch that cuts out the tonestack (everything after C9 and before C12 on the GGG schematic) you'll get a much fatter sound.

The simplest mod I've found so far to control the mids is replacing the 22k resistor to ground with a 10k + 100kA pot.  This allows adjusting the depth of the mids from even deeper than now to nearly flat (just 3dB notch depth).  This is a very easy to implement mod on a prexisting BMP.

Definitely learn how to use the Duncan Tonestack.  The values I like are 15/15K resistors and .01/.022uF caps.  This yields a Marshallish mid-range dip smaller than the stock stack.  Infinite variations posible.   :icon_cool:
