Hi All
I've been looking over the schematics and gutshots of the Mutron BiPhase here
http://www.crazy-patroche.com/article-mu-tron-biphase-musitronic-plans-et-clonage-108652497.html
Question I have is how and where on the control board schematic are the connections to the expression pedal? They seem to be missing from the schematic and I can't figure out where they need to go. If they aren't there it kinda makes Switch 2 redundant doesn't it?
Cheers
Phil
hello and welcome, PMowdes. it looks very much like the lower left hand corner - "PEDAL IN J6-1" - which also appears to not be shown, is the expression pedal input.

Thanks,
After a bit more digging I think I have the missing part of the puzzle. Looks like the schematic is wrong with respect to the pin out on J6.
It should be
J6-1 +15V decoupled
J6-2 expression pedal in (this is incorrectly labelled J6-1 on the schematic)
J6-3 Phaser A switch
J6-4 Phaser B switch
J6-5 Ground
there's a expression pedal schematic here http://www.freestompboxes.org/viewtopic.php?t=14002&p=162986
"here" is the place with no name, place-non-grata, my foreign language is non- existant, but they don't allow us to link to the site that shall not be named.
but we all know where "http://www.....org" refers to when we see it.
