A slightly smaller point to point layout for the Sola Sound Tone Bender MKIV than the other in my post (for bigger mojo parts). Of course you can build any Tone Bender MKIII or MKIV from this layout.
SOLA SOUND TONE BENDER MKIV - COMPACT POINT TO POINT LAYOUT
NOTE: voltages shown are approximate, and HFE and leakage can be somewhat variable. From what I have tried, you definitely need a bit of leakage on Q3. I found breadboarding this circuit more useful than reading opinions on the internet.
TONE BENDER MKIV - BUILD IN PROGRESS
OC76 for Q3
2 x Micro 2N2996 germaniums for Q1 & Q2
Soviet GE Diode
ON THE SCOPE
Signal: 440hz sine wave, approx 130mv TRMS
Setting: Fuzz on full
3.3nf capacitor in tone control, instead of 2.2nf
Tone 50%
