I notices the two holes beside the + - are not labeled on the pcb. I am assuming they are GND? thanks Pb

Looking at a buffer schematic, the G is in yellow below. But I am assuming that the drain and source are interchangeable since they are not labeled. While I am at it, can a electrolytic be used in C2 (neg towards out)? thanks Pb

I am looking for germanium diodes for a foxx Tone Machine build. Pedal pcb has d9b https://www.pedalpcb.com/product/a8002/ Are they ok for build? Thanks Pb

Typical fuzz circuits use a gainier transistor in q2. I noticed that the schematics i have seen for the foxx tone master use all the same transistors 2n3565 , 2n5088 or 2n5089. Is there any value in using a higher gain trans in q2? Eg 2n5088 q1 2n5089 q2 Thanks Pb

Any recommendations on wire to use for pedal building? I have tried cloth 22awg, and the plastic/vinyl 22awg. I find cloth a bit of a pain to work with but it looks good. The plastic is a bit rigid. Anyone using 24awg...

Hi I think the pcb silk screen is right but i thought i would ask. The layout document and pcb differ for r10 and r8 The 1 m resistor looks like apull down on the output. The trace on the pcb looks like that is the correct r10. Thoughts? Pb

First time using a charge pump. I am looking into building the sunface: https://docs.pedalpcb.com/project/Sunflower-PedalPCB.pdf The tl1044 takes in +9v and pin 5 puts out -9v. Is the ground still the (-) that comes in or the (-) below the 47u cap that joins -9v to ground? maybe dumb question...

I built the thermionic beod clone. Great pedal but noticed the presence pot starts to sound scratchy/spitty once turned half. Just a bad pot and replace it? Thanks Pb

I am wondering if the reverb pedals with fv1 chips need special programming to be useful. I thought if they had an algorithm preloaded that is all you need unless you want to roll your own. Is that correct? Thanks Pb

I am wondering whether i should build a reverb pedal like https://www.pedalpcb.com/product/pcb058/ Or just buy a used one like the ehx oceans 11. Or maybe there is a better option on pcb? My use case is simple hall/spring reverb since my amp doesn’t have it. My first instinct is to build it...

Hi I am looking for software to draw schematics. What sw does pedal pcb use? Or is there one the forum members recommend? Thanks Pb

This is just feedback based on the last few boards i built. Off board wiring is where most of our problems happen. Is it possible to design the the pcbs with a bit more room for the 4 off board wiring holes: + - gnd grd I find they are very tight at the top. Also if (when) they break off...

I have the board all together and am biasing the j201s. I noticed that the bottom right trimmer is cranked down all the way and i am still seeing 8.6v. The others are all 4.6ish. Is this guy not meant to go to 4.6? Thanks Pb

I am building an m800 tonight. Noticed the trimmers have 5 holes. Assuming they are for larger trimmers as well? I am using 3326 which fit the upper 3 holes. See attached. I note that the doc only has 3. Thought i would ask to confirm. Thanks Pb

Hi all Is there any mod/resistor change for the sunflower to play nicely with EMG pickups? Or other high output humbuckers? I have the guitar vol turned way down. Maybe that is just a fuzz thing? Thanks Pb

I am looking at the sunflower fuzz schematic. There is a 50k clean trimmer on it but pin 3 doesn’t look connected. Is it not connected 3-2? Like the bias trimmer? Here is the full schematic https://docs.pedalpcb.com/project/Sunflower-PedalPCB.pdf Thanks Pb

Hi all, I am wondering what the 1m ohm res (R5). does in the silismile circuit: https://docs.pedalpcb.com/project/SiliSmile-PedalPCB.pdf I have seen a few designs that don't use it, but I think all pedalpcb boards do. A lot of designs don't use the 47uf cap on the power rail. That one make...

Hi all I have the silismile working well when the bias pin shows 4.6v. I tried putting a 6k resistor group (4.7k+1k+330r)in its place and i get the almost the same bias voltage. There is a 1k resistor beside the trimmer. Wondering why that 1k is needed with the trimmer right beside it. Why not...

These plastic 4 lug mono jacks are a lot cheaper (.99 vs 2.59) than the usual open jacks, are they suitable? https://nextgenguitars.ca/products/generic-1-4-mono-switching-jack-4-lug-solder.html I am wondering how to solder the 4 lugs. Usually I use this type which has only 2 solder points...

I am starting to bread board now and thought the fuzz face was a good place to start. The silismile looks interesting and close to the original: https://docs.pedalpcb.com/project/SiliSmile-PedalPCB.pdf Question, the separate lower power section in the schematic, if I am not using a stomp or LED...
