Hey @Robert ! I usually post stuff when I'm wanting something or need it so here it goes! 😁 I have not found any definitive resources regarding a trace of the Kilt V1 or V2. Pedal & PCB builders are limited on time and this just seems to not get the attention. I understand they are basically...

I used Vishay 1N5222B 2.5 V from mouser electronics found here: https://www.mouser.com/ProductDetail/78-1N5222B

The tone is exact with one exception. There was a slight high end presence that the original had (not what the treble knob does, but a high end presence similar to what the high end switch does) that the clone could not match at any setting. Most likely component tolerances I suppose! It was...

Would love to see a JHS Kilt V2 become available as a PCB! It's one of the most widely used ODs in P&W music. Probably in the top 5.

Thats awesome! What I am wondering is if TRS jacks can be used separate each side for a loop switcher. This would be a super helpful option. Of course, I could just get the separate pedals, but the dual drive saves space... and looks cooler! :)

Hey all, this pedal has now been fixed. The issue was the Q2 2N4401 transistor was bad. Robert (reverse engineer) thank you🙏 for your support. One of the main helpful ways I located the issue was by continually using steel tweezers and poking around to see what changed the sound or caused normal...

Hey yes, thank you. I did this with IPA and it all cleaned off very well 👍🏻 the problem still occurred after the cleaning

Okay, interesting stuff. This is all new to me so I youtubed how to do the reading. Also, I'm not sure how to communicate the measurements. Q1,2, 3 correspond to the pedalpcb build docs. E = emitter, C = collector. Here's what I've found: Q1: E = .649 V C = .633 V Q2: E= 0 V C = .593 V Q3: E...

So I have an original daily driver that I bought since I lost hope in fixing this clone so I was able to compare them. I wonder if grounding this transistor (I did solder a leg to ground) removes it from the circuit? I don't have enough knowledge to know that, but the real daily driver sounds a...

If I bridge the ground next to it in the far corner and the right leg (or left leg) of the transistor with the steel tweezers, the noise goes away and all is perfect! I wonder why this is happening. Should I just wire the ground to it or replace the transistor or something else? Thank you Bob

Hey y'all, I may have discovered the issue or at least something that may lead us to the solution. When I touched the right leg (looking at the flat face of the transistor) of (Q3 2N4403 BJT transistor, PNP TO-92 from build documentation) with steel tweezers, the signal still sounds good and the...

Just purchased another 7660 to see if that is the issue. Here is the version I'm using: https://www.mouser.com/ProductDetail/968-ICL7660SCPAZ

Just checked all of the resistor and values, all orientations of caps and diodes is correct as well. I don't have an extra 7660 to test at the moment.

Just cleaned off all of the remaining flux from the board very well with IPA and the problem is still occuring. I've also inspected every solder joint to make sure no leads are touching, except for under the IC sockets.

I've just updated the pictures in my google drive for more clarity. I took the LED off because when I touched the LED wires (the insulated part), the noise floor was reduced. Removing the LED did not impact the noise that you call oscillation. Also, when I touch PIN 8 of the 7660SCPAZ with my...
