Re: the boss sd-1 bypass problem... possible fix for you.

[wampcat1]

Just got off the phone with Tim from tcjeffects.com...apparantly he's had very good luck with eliminating the bypass bleed through by changing r2 from a 470k to a 560 or 620k resistor. Anyone want to give it a try real quick and report back?

I've used a 620k on every one that I've modded ( 25 ) and it does give
you some more clarity when bypassed/engaged.
It's just increasing the input impedance, so has no effect on the "bleed through" I'm afraid !!
Reducing the pair of 22k's to 1k or even jumpers sometimes helps, but
I've had to replace the switching Fets a few times to solve it.
The old 2SK30's and 2SC1815's seem a bit "poor" at turning off properly!
