Terrible title sorry. I’ve noticed that amongst the the switch pads on PCBs, there is usually one square pad (DPDT etc). Although I note that Pedal PCBs ones don’t have this, only others. What is the reasoning for having a square pad? The orientation of the switch doesn’t matter? Although I’ve...

Hi all, I'm looking to streamline the wiring process and so want to board mount my power jacks. All I can find are square / rectangular ones (https://www.taydaelectronics.com/hardware/dc-power/dc-power-jack-2-1mm-barrel-type-pcb-mount.html), but this creates a problem when drilling...

Hi all, Designed a few pedals in Eagle and got them to work pretty well, but these were basic and relatively low part count. However, I have drawn up something that is much larger and I've lost the confidence that I have everything covered. Has anyone used a service that can check over these...

Hi all, Tearing my hair out with this one. I’m only getting clean signal when engaged. I’ve switched out all the ICs and checked over too many times. Is there anything that you guys can see that I’m missing? Thanks for looking.

All, Interested in building up a promethium with no potentiometers. They are only going to be dimed anyway. Is this as simple as just soldering a resistor that corresponds with the potentiometer value? Which pads do I connect the resistor too if this is the case (there being 3)? Thanks for any...

Hey all, I’ve been looking a at few pedal designs and it seems that some designers have used non-polarised electrolytic caps in their circuits. To my uneducated eyes, it looks as though a normal polarised cap would would in it’s place, but obviously the designer would use a common component if...

Hi all, I’ve been looking at projects using LDRs and want to understand their function and effect on the actual sound. Why use these instead of standard resistors? Do they have a variable effect? How does this work if the light from the led is constant? Sorry, bit of a ramble, I love the...

Hi Guys, Keen to do a combo build of 2 pcbs in a single enclosure, operated by a single switch. So when the switch is activated both effects are on, switch off then just clean signal etc. Would be awesome to get an order switcher in there too. I feel as though this isn’t that hard, but I’m...

Hi guys, I've done a few builds, and I'm sure this is a super dumb questions, but I'm having trouble figuring out what this diode is supposed to be. Is this just a 5v6 zener? Is there further info to this diode? Will any 5v6 diode work? Thanks for any help. Cheers
