Apologies and thanks for the response. I will post in Troubleshooting. To answer your question, I built it from this layout but with an MPF4393 in Q1 and an MP38A in Q3: https://tagboardeffects.blogspot.com/2013/08/bjfe-bearfoot-pink-purple-fuzz.html?m=1

Hi Chuck. I have just built the three-knob version (yes, silly me, it was before I realised there was a refined version) on stripboard, but I'm getting oscillation with the fuzz pot in the higher regions on certain spots of the Nature pot. The oscillation remains no matter Q3 (I have a load of...

Did you ever find a solution to this? I just built a three knob version and I'm having the same issue with a variety of germanium npns. I have double-checked pinout and I am putting them in the correct orientation (I'm socketing). It's only at some points in the fuzz and nature controls but the...

The depth pot wiring needs to be mirrored from my take in post #23 above. Works fine now. Very nice-sounding pedal.

So I wired my depth pot like so... Do you know why the depth knob is working in reverse?

It's alive! I desoldered the whole board and migrated the components to a fresh piece of stripboard. Soldering went much more smoothly with magnification. One thing though: my depth pot is working in reverse: most intense at fully anti-clockwise and vice versa. The image shows how I've...

Yeah, my eyesight is definitely an issue soldering to stripboard. I ordered a magnifying visor, which unfortunately arrived when the board was mostly done. I will concede that the soldering is on the messy side. That said I'm getting continuity everywhere I should, and no continuity everywhere I...

I guessed that the 3PDT board might be the problem so I rewired it directly to a fresh 3PDT two days ago. I had a look at the schematic in the BYOC build document. It's practically illegible. In any case, I'm not terribly fluent in that language though I'm slowly working on it.

I can't get it working anyway. I think I might hate stripboard.

Annoying. I'm sure you've maxed out the level trim pot?

Yes, I have more or less finished it with the small issue that it is not working. The LED is flashing and the speed pot affects it but no sound. I'm not really sure how to wire the footswitch so that might be the issue.

I think that's jack in/out?

Right, but where on the main board are the corresponding BI and BO connections?

If you're changing from a BC549, learn from my mistake: the pinout is different for the MPSA13. It's rotated 180 degrees.

I recently changed my Q10 for an MPSA13 and am sorry to relate it made very little discernible difference to my ears. I recorded a few phrases on a looper for the Before reference and it sounded pretty much the same after the Darlington switch. Try it though, as always YMMV.

I'm trying to translate this stripboard layout diagram to a 3PDT wiring board and my head hurts. Can anybody tell me where on the stripboard to connect the switch board's in and out (BI and BO)?

Aha, basically creating your own diffused LED? I've gone up to 36k and it's an improvement but still surprisingly bright.

And I probably shouldn't have taken it as a challenge slash personal affront when the Vibe documentation warned that this was not a project for beginners. That being said, I now have the speed pots wired correctly and the bicolour LED changing colour with a click of the speed 4pdt. Both the...

No problem. I appreciate your help.

So I have the bicolour LED working now but my speed pots are both working in reverse: fastest at fully counterclockwise, slowest at fully clockwise. Am I reading your diagram incorrectly? I assumed you were showing the speed pots from the underside (ie not the shaft side) with the dark purple...
