Modding Other Pedal Builds With GPCB Boards

[Big O]

Since I have pretty much stopped building new pedals, I have gone back to modify old builds using GuitarPCB boards, primarily 3PDT boards I had left over.  I had built point to point wired pedals that were without LED indicators and DC power jacks, so I decided to make them a little more user friendly.  The GPCB 3PDT boards made wiring the pedals much easier.  Thanks to Barry and GuitarPCB for coming up with and supplying these very useful boards that makes wiring pedals a breeze.

First is a PNP fuzz that I had to convert to NPN by switching out PNP 2N3906 transistors with NPN transistors of similar gain (approximately 160hfe and 180hfe), reversing the polarity of an electrolytic capacitor, and reversing the wiring polarity.

Point-to-point is above my level. I do like looking at the pieces that become essentially art, though.
And yes, I have also made a point of tossing some extra 3PDT or various mod boards in my cart whenever I order. One the few pedals I’ve made from diagrams, they’re still by far the easiest way to wire up a switch. Love these things.

I agree with MathU41 on the point to point circuits. About 3 levels above my pay grade! BTW, great looking group of pedals!!
