I've made a couple Moonshines on stripboard a while ago that both pop really badly. I'll have to revisit them with and see if Mr Black's tips help any.

Fair point about ref des - that should become a habit even when handwriting when sharing schematics. Those mods are just about right. For my own build I've gone further and added a buffered voltage source and pickup simulator - haven't gotten the boards made yet. That goes outside the bounds of...

Yes, that schematic isn't faithful to actual builds. It's based on someone's conjecture that the inductor in the schematic would be a standard wah inductor (based on photos of actual boards this is false). That person attempted to recreate the response curve of a wah inductor using a 100mh...

The tone switch on the HPTT probably switches out capacitors in a low-pass RC circuit. You know, you could probably reuse the "voice" toggle and the diode spots on the Twill board to recreate this. If you tie a 10K resistor in series with C2 and put a 15nF capacitor in either D3 or D4, and a...

I'm not sure about the tone toggle off the top of my head. Regarding the clipping switch, here's Lovepedal's description of how it works: So you'll want to find out which clipping diodes are the High Power Twin setting and set it there (I suspect it's just the pair of silicon diodes). Also...

After leaving it 18 hours then playing on it for 10 minutes we've got: - Q1C = 3.87 - Q1E = 3.93 - Q2C = 4.81 Stick a fork in it, we're done (recorded into Garageband using a clean amp simulator):

That's a "K" Yep, you're right. It does "something" but it's subtle and, honestly, not worth including. In fact - I relistened to the demo I recorded last night and decided I really didn't like where this circuit ended up. So I started taking parts off and wound up with something a little...

Well I'll be ding-dong-danged, that IR LED sure isn't doing a thing. In my experimental-swapping-fervor I must have put it there to try it out and thought "Hey I like this" and didn't think any more about it. I've swapped it for another of these goofy Soviet GE diodes, so here's the FINAL final...

Yep, that's how it's worked for me. Are you unable to replicate it?

Final update from me on this schematic - I tried a buffered 1.5V supply using a TL061 and it sounds amazing. Lots of harmonics, some octaves, a usable gate control, and a bonus option to put a potentiometer on the voltage divider for saggy sounds. It also now can clean up (a little bit) with the...

Sorry if this is taking over the contest thread - I thought it'd be a fun circuit to show off in this context considering the number of parts involved. Yep my schematic is built entirely on conjecture, hearsay, and the best guesstimates of forum posts from over 15 years ago, lol. Here's the...

The original used silicon "BC" devices based on images. I put together the schematic based on images of the original circuit board and values people listed in that thread I linked. It was mentioned, and I can confirm, that higher gain devices work better that lower. Only one guy in that thread...

I'm interested in all opamp overdrives!

Here's another fuzz that comes in at 29 pieces including all the stuff for regulated voltage. There's not a whole lot of documentation on the internet about the internal fuzz circuit from old Messenger guitars. A friend of mine mentioned Grand Funk Railroad's Mark Farner's guitar tone was his...

I need to get back into it. I have a bunch of extra PCBs from an old project where I made a version of the VHS (JHS VCR) but with a Golden Fleece for gain (not a clean boost), tremolo instead of chorus, and an extra spacey reverb. I'm hoping to swap the reverb for a phaser to pair with the...

I have a varitone of sorts in a Gretsch and I like it a lot. I don't have an inductor or transformer on mine, though. 6 different capacitor positions for increasingly dark tone, a bypass position, and a high pass position. The high pass is really worthwhile, in my opinion. On filter'trons it's...

That's really neat - I'm going to have to try that capacitor switch. Maybe more useful than just-another-diode-switch? More interesting, at least.

I'm going to get this one printed up. Maybe it'll be delivered by the deadline? 🤷‍♂️ Aiming for 1590B with top jacks and a whole bunch of mojo. Apologies for the airwires, I removed the ground pour for the image.

Revised and making noise! I had to replace the low-gain GT403 Russian transistor - I'm not sure how I got these to work before. They're very unpredictable even if they test well. Instead I'm using the lone OC75 I have in my stash and yeah, it sounds great. Apologies for the cellphone sound and...

I recently built a stock Bee Baa and was amazed at how well it sounded on a low-tuned guitar. It seems a fairly niche circuit so I'm not sure how many variations there are available as a PCB, but there are a few stripboard layouts going around: https://dirtboxlayouts.blogspot.com/search?q=bee+baa
