The ED-1 and the other pedals in Marshall's metal beetle series use something that they describe as "passive bypass", but it's not even close to true bypass. Definite tone-suck.
Maybe we could use the inbuilt DPDT switch to make something like Jack Orman's Millenium bypass, which would make these pedals really kick arse.
It's all in front of a buffer and dat'z it's whole purpose, to *isolate* it.
I do own an Ed1 and except for changing R19 (the 10k before level out) mine is stock.
This makes the level pot far less sensitive.
I have also been testing some comp circuits and here is what I've found so far.
If you want to change the *Comp Depth*, double up the diodes (D2,3) or add a switch and flip between say a pair of leds and diodes. that will give you a soft /hard Effect.
Also the *Release Time* can be altered by changing C15 (10uF). hangs off the base of Q5.
all subtle stuff but interesting.
