Pretty close to an MXR Phase 100 as I expected but slightly different.

All component numbering is the same as it is on the board.

Enjoy!

There´s a sucker born every minute - and too many of them end up in the bootweak pedal biz.

Very nice drawing indeed. There are no static phase all pass sections - the MXR 100 has these I think - from memory only, I could be wrong.

Any luck finding dual LDRs like that?

Thank you captain obvious. That's what I'm having to do. I have a need for a dual LDR like that which would be matched already rather than me trying to manually match up 2 LDRs with 1 LED. I haven't been able to find them anywhere.

:lol: hard to come by ...i usually just buy a bunch and match em as close as possible....for one or two build no worries !
I am usually lost for Led color choice tho ... red/green for less and yellow /orange for much more.... a simple rig to couple and simulate the led/ldr combo is the way to go for me :wink:
