Note, in the board mounted footswitch version In/Out pads refer to the jacks, and Send/Return refer to the effect in/out.

Optical Bypass
Here's another alternative to the 3PDT for bypass wiring. It's based on the method VooDoo Lab uses for bypass and uses a optocoupler to achieve true bypass using a DPDT. I've drawn up 2 different layouts for this: a standard perf/PCB layout, as well as another PCB I did in Eagle with the footswitch board mounted. There are extra pads so the compact or the larger DPDT footswitch can be used, as well as an extra pad for the resistor so 1/8th or 1/4th watt can be used.
Very cool. Does this require a latching or momentary switch to work properly? I'm guessing latching, due to lack of PIC.

DeleteI've wondered why you'd choose this over say... a millenium bypass. H11F1s aren't cheap!
ReplyDeleteuff! h1f1m 1,5€
ReplyDeletewhat software did you use in making pcb?
ReplyDeleteif you read description for the second pcb he used eagle. for the other diylc, you can look at his useful videos
DeleteThanks man. Great job. Do you have a good tutorial for eagle? Link please, if possible ;-)
ReplyDeleteHello, the perf version is VERIFIED with H11F3 optocoupler

ReplyDeleteWould it be useful to eliminate any problem of popping "when turning the effect on or off?
ReplyDeleteh1f1 is obsolete, end of life production.
ReplyDeleteCan i use 4n35 instead of h11f1?
