I’m trying to build a Muroidea for a friend of mine. He wants it to have no external knobs. He suggested trimpots on the inside to save space. What type of pot is a trimpot: Logarithmic (A) Linear (B) or Reverse Log (C)? Would it just be easier to use regular eyelet lug pots and wire them...

I’ve finished the mini KoT and it sounds great but I can’t get the right LED to work. I’ve pulled it out of the enclosure and am testing just the board plugged in. Replaced the LED and no luck. The 4k7 LDR seems to look fine. Any thoughts on what gives? Thanks in advance! James

Ok, so I finished the XC Phase and put it onto the test board. I get bypass signal, signal when activated, LED on when activated, but no phasing. Any good spots to check? I saw in another forum Pin 7 of IC3 to check for the LFO functionality. Any thing else I should check. Do I need to adjust...

Hi all, Working on the XC Phase. I broke down and bought the matched quad pair of 2N5952 from Small Bear. I have version 2 of the PCB am I correctly orientating my Q1-Q4 correctly facing upside down as seen in the picture attached? Measure twice, solder once! Thanks James

Hi, I’m about to build the XC Phase and have a question about the JFET’s. How do I match 4 SMD JFET’s? Do they already have a close enough tolerance as SMD, or do I need to match them somehow? Google results were telling me to use some kind of jig to measure various stats, but have no idea how...

Hi all, My buddy just finished building a Daydream and it has no sound when activated. I put it on the PedalPCB test board and I have power and I have bypass but silence when engaged. Last time my friend had not soldered enough on the switch. I’m wondering if the same thing happened again. I’ve...

I came up with this idea when I had to drill 10 pedals in a row. A simple “bracelet” with different parts as “charms” that you can use to test holes for spacing. It includes an input jack, pot, SPDT switch, and 3pdt switch. I need to add a LED as well to it. The only thing it’s missing is a DC...

Hi all, I built a Irrlicht OD last week and it worked fine. A buddy who is new to building just built one yesterday. It tested fine on the PedalPCB test board. All pots worked and normal volume. When we went to box it up in the enclosure the active sound is barely there and hard to hear. True...

Hi all, Back from a long building hiatus. I have a question on the pastel. It has a spot marked input and ground and output and ground up near the top of the board (red circles) Is this what goes to the input and output jecks? Not from the footswitch as usuallly you do? Second question is...

Hi, I build a leprechaun about a year ago and it worked fine for a while. Recently went to mod the exp control and I’ve been having the weirdest issue. Everything works fine and sounds chorused and woozy. And then it will stop the fx all together and just pass clean. I can get it to replicate...

Hi all, put together the Ocelot Octaver tonight and plugged it into the brand new Auditorium testing platform. When I plug it in, it turns on and the volume work, but neither octave works. I’m pretty sure I have version 1 so I did the IC mod of the legs per the instructions and soldered and...

I've been looking high and low for 20u electolytic caps and am not having much luck for the Twin Face. Will 22u work? The only 20u I can find are 300v or higher, which probably makes them too big to fit on the board. Any thoughts on if 20 vs. 22u is a deal breaker?

Hi all, built the Loon Tremolo and it sounds great. However, I went to swap out the LED colo for a customer and tore out one of the pads and the wire from the PCB. I managed to work the ring of the pad back around the leg of a new LED but it’s not working :( looking at the schematic LED 1(the...

Hi all, A few months back, I built my first order switcher/looper based on a schematic that was shared here. Works great to have 2 loops I can turn off and on and switch the order as well. The only downside is that this doesn't have any LED's or power as it is just the 3x 3PDT's wired to the...

This might be a dumb question, but do I need to use different power (I.e. 24v DC) when I switch from 9v to 24v on the Duocast. I wasn’t sure if that switch was just manipulating the power voltage internally or something you need to change power sources for. I ask because the right side (24v?)...

Hi folks, finally got the Duo-Phase up and running. LED’s for the LDR’s power on and I get signal, but it’s just totally distorted and sounds like a synth almost. I tried tweaking the trim pots to no avail to lower the gain. I’ve included photos of both sides of the board if anyone has any...

Hi all, Im building a double booster that is half SHO and half Amentum (EQD Arrows). I’d like to have a tone stack PCB for mid boost as well. I realized that my previous wiring up the tone stack after the Dboard of the Arrows meant that the Mid pot was always “on” regardless of the 3PDT for...

Well this is a first. Everything else works fine in this Amentum boost that’s a combo with a SHO and a tone pot. But I can’t get the LED to turn off and on. It just stays on. Weird. I assume it’s a ground issue. I tried retouching the GND leg from the PCB to the D-board on the 3PDT. Any other...

Working on a Boss OD clone and it’s asking for a MC3404 or I can also use RC3404. For the life of me I can’t find either of these online. I keep getting MC3403 and variants. Does that work? I can’t even find data sheets for the MC3404 but they’re both 14 pin chips, so I’m guessing they’re pretty...

I normally use a 2.1 DC jack that is the “standard” size. See on the right in the pictures below. What you’d get from Tayda. I’ve bought the Lumberg style DC jacks (On the left) from PedalPCB so it would 1) fit his pre-drilled enclosures 2) allow me to use the 3in1 DC board to power multi...
