Tone control minimum: The tone control can get pretty dark at its minimum settings. RX2 has been added
1
to counteract this, allowing you to raise the minimum position of the control. 1k is a good place to start for this.
Capacitor type: C7 was a tantalum in the original, but I included space for the larger film caps. Polarity
2
markings have been added to the silkscreen in case you want to use tantalum.
Part of the voltage doubler circuit. You can omit these parts if building a straight 9V version.
3
Germanium diode: Any germanium diode should work fine here—the exact part number isn't important. This
4
diode was added in V4, so it can be jumpered if you're building a lower version number.
LEDs: I recommend using red diffused 5mm LEDs for the second clipping option.
5
Drive pot value: One commercial version of the modified VLOD switched to a 1MA pot for the Drive control.
6
General consensus is that this was not an improvement and the pedal loses its character above 50%. I
recommend sticking with 500kA here.
Tone pot value: Early versions of the modified VLOD used 25kA for the tone control and 100n for C8.
7
Volume pot value: The first version of the modified VLOD used 100kA for the output volume control. The
8
500k gives a lot more output volume with the downside that it's a little harder to dial in at lower volumes.
Additional Part Notes
• Capacitors are shown in nanofarads (n or nF) where appropriate. 1000n = 1uF.
• The PCB layout assumes the use of film capacitors with 5mm lead spacing for all values 1nF through
470nF. I prefer
EPCOS box film
• Potentiometers are Alpha 16mm right-angle PCB mount.
• I recommend using
the board and prevent shorts. If you don't use these, use some electrical tape or cardboard to insulate.
