Mentioned in the DMM thread so making a new one
The 90s poly reissue isnt true bypass, and doesnt have LED indication
TO make it LED indication, you typically need to replace the DPDT switch that is in there:
*note I already replaced the DPDt with a nicer alpha brand version. Yours might look different....
With a 3PDT switch (classic blue 9 pin dealio). Wire it up as per the DPDT. I use a cool O ohm resister as the jumper, but you dont have to:
Next take the red wire that is connected to the PCB at the point marked "LED" and run that to the central lug of the lefter pole of the footswitch. Run another wire from the pole of the footswitch from which the output connections from the PCB are wired (on my pedal, the red and yellow).
As such:
This will allow LED indication.
I find the bypass on mine acceptable. True bypass with LED would require a 4PDT switch I think.
Enjoy!
