Been on a parallel dirt box kick, and someone happened to request on of these, but wanted it louder with a bit more range, so here's what I did

1000035623.jpg
Mods -
  • All caps in signal path increased from 22n to 47n
  • Fuzz transistors are 2N4123 (Q1 hfe 87, Q2 hfe 74)
  • C8 reduced to 22n
  • R2 reduced to 1k
  • R13 reduced to 2.7k
  • C11 increased to 220n
  • C2, 4 & 5 increased to 150p
  • Dirt pot reduced to 250k
  • Volume pot switched to 100kA
  • Spikes pot reduced to 20kW
  • All clipping diodes swapped to red LED (1.7vf)
 
Very nice !

I built this circuit too and i like it very much.

If i remember correctly, the distortion is close to the DOD 250, and the fuzz is a special design for this circuit.

I wonder about all your mods, how are they affecting the circuit ?

Caps in the signal path increased on the fuzz side to hit the transistors a little harder, get it closer to FY-2 textures. Used them on the distortion side because I already had them out

C8 reduced to leave some more high end intact on the fuzz side

R2 decreased to let more high end and signal into the input

R13 and Dirt pot reduced to allow more total gain, and reduce the amount of travel before the fuzzies happen

C11 increased for more lowend on the distortion side

C2,4,5 increased because I couldn't find my 120p

Volume pot switched to audio taper for smoother sweep

Spikes pot reduced to balance the range a bit more

Diodes changed for more volume and less compression
