I've drawn up 2 different boards–both have the LED and the LED resistor on board, but one has a MAX1044-based charge pump for when you're building a positive ground effect. It has polarity protection and power filtration on-board as well.

3PDT Footswitch PCBs
Got a request for a PCB to make wiring up 3PDT footswitches a little less messy. There seems to be about a dozen ways to actually wire up an effect with a 3PDT, but I went with this wiring scheme drawn up by Bumblebee over on DIYStompboxes as it's fairly neat and efficient. The effect input is grounded with the effect is bypassed, which eliminates any oscillation that might happen in pedals like the Small Stone.

might have another suggestion for this nice little board (makes wiring much cleaner and simpler)
ReplyDeleteone that use a icl1660 as its cheaper than the 1044 and one that could be built with a 555, to use with fuzzes with negative ground so they can be chained
How do i find the PDF file if I don't know who created it ? No search feature for that.
ReplyDeleteWhere is the pdf file of this?
ReplyDeleteUtilities folder
DeleteIs this true bypass.?
ReplyDeleteYep
DeleteWow that was quick..thanks
DeleteWhat's the diameter of the drill bit to drill the 3pdt holes.?
Delete1.5mm (tight fit)
Deleteis the 2K2 resistor a CLR(for the LED)?
ReplyDeleteYup

ReplyDeleteWhat size do I print? since when I print the PCB is too small
ReplyDeleteCan this 3pdt pcb solve the popping sound problem?Has been plagued by this problem
ReplyDeleteCould be cool to have board with bigger hole for switch with solder lugs.
ReplyDeleteAnyone have noise problem with 7660s chip?
ReplyDeletewhere the pdf of this ?
ReplyDeleteShould be in the Utility Boards folder
