Here’s the build I’ve draw to use with some of my higain layouts like Dr.Boogie, or BSIABII. It’s unverified. It’s single knob gate with the switch – I have no bloody idea what switch does, I’ve downloaded the original layout long time ago and I don’t really remember from where, so no person to ask. From the picts of the original unit we see no extra switch, so this one is an mastery The idea of using this layout to me is to activate it without the toggle/stomp switch, just use a pot with integrated DPDT. In O position this circuit will be omitted, anything above activate the gate… Well, it’s just my idea to use it, this way you save a space, but doesn’t really matters how you use it really.
I’m not sure If this is any good for higain pedals, as I heard it’s to slow, may be some of you knows how to make it faster, or perhaps someone point me better single knob project to transform
GAIN: 1M-A (or 500K)
I’m not sure about 69. In GGG project files we see 0,1uF cap, while in most (all) of YAFF’s I’ve seen there is 0,01uF. Also I’ve changed 1k resistor in line with Q2 bias knob to 4,7k as this is what works better to me. Have a look and tell me what you think. Trimm is 10k, Fuzz Control 1k Lin, Input Bias 50k llinear, Contour 1k linear, Vol 500k log.
As per 70 – again, confusion starts!
Electrolytic from base of Q1 should be 2,2uF in all FF clones, and here is – according to GGG project files 22uF… So I’m asking WTF?
as per layout, 10pF/1M combo can be set under the board to save 2 tags
