@MichaelW - did you happen to see this post from PaulC himself, where he says R9 (or maybe it's R10) should be 3k3 instead of 4k7? I built mine a while ago, not sure if the PCB silkscreen or BOM has been updated.

If I sold boutique pedals commercially, I’d publish the schematic publicly. But I’d also goop every pedal that went out, just to mess with people. I’d also do multiple layouts of the exact same circuit.

I agree, you have to be very sparing with the acetone. I always clean my enclosures first with alcohol, and that didn't seem to be sufficient. However - having said all that, based on this comment in GOTA's thread, I realized I do in fact need a new drum unit for my printer. And I did one...

@MichaelW - you built both the Old Fashioned/Major Overdrive and the Diamond Peak/Hybrid Fuzz Drive?

I have five of these PCBs, minus the one going to @bluedmc777, I have four left free to whoever wants one. @dcfvgb - if you only need one I can save you the fabrication cost.

@HamishR - did you actually use 2n5172 transistors for Q2 and Q3? If so, did you happen to measure their HFE? I'm fairly sure that's exactly what Skreddy/Animals used in the COTS Major Overdrive I had. But typically low-gain transistors (<100 HFE) are encouraged in these designs. I have a...

@Robert - looking at the schematic, is that really how VREF is wired? That unused opamp just begging to be put to good use, and he almost used it for a Vref buffer. Almost. Isn’t there another JRocket design that has an unused opamp with one of the inputs left floating?

I have made several boards for this circuit. Take a look at my build reports for the few revisions I’ve done. I’ve sent boards of this circuit to a handful of forum members. I’m happy to send out more, just shoot me a PM!

I have a special place in my heart for organic polymer caps, because those are, in a way, what got me into DIY audio electronics. Before I got back into guitar, diyAudio was my regular hangout. I got my feet wet in that hobby by buying super cheap audio devices (amps, DACS) from China, and...

Looks great! It's hard to tell from the picture, but how much clearance is there between the output jack and the volume pot? The "tip" portion of the output jack does move a bit when the cable is inserted/removed. You might want to do that with the back cover off so you can see how much...

It might, but I can only guess. My hypothesis with the light acetone wipe is that there is some residue or possibly even deliberate coating on finished enclosures that isn't particularly compatible with the GW1-Pro glue. What inspired this thinking is that I had some really bad transfers that...

When I first got into these waterslide decals, I was using the W1+ glue, and generally had pretty decent results (based on GOTA's original tutorial). When I ran out, I ordered the newer GW1-Pro glue, and I've had more mixed results. I've generally had pretty good results with this glue on...

What printer are you guys using? I've got a Brother HL-L2340DW, which I bought over twelve years ago. What I've found is that the middle 1/3 or so of whatever I print is nice and crisp, but the printing gets a bit fainter as towards the edges. It seems to do this even with a fresh, official...

Is that a Corsair box? Are you also in the middle of a PC build?

I'm pretty sure your original how-to guide on the Sunnyscopa film-free waterslide decals is what got me into it. Using your guide, I generally had pretty good results. However, since using their newer "GW1-PRO" glue (aka transfer agent) I've had mixed results. I wrote up a collection of notes...

I don't think this is accurate, actually. The Bluesbreaker family of circuits have variable gain in the first opamp stage, which in turn drives the second opamp stage. Whereas in Chuck's Dark Esbat, the first opamp gain stage has one of three discrete gain settings (based on the "mids"...

What about R3/22k (channel 1) / R13/10k (channel 2)? Is that to make the gain when the drive pot is all the way down roughly the same between the two channels?

Anything worth building is worth over-building, IMO!

I use LEDs like this. I've seen them called "ultra-bright" or "high efficiency". Every now and then I do a PPCB build and forget to replace the stock 4k7 with something much bigger and get nearly blinded on the first power-on.

Is there a specific reason for the sawtooth edges of the PCB? Great looking build, as always! I love the loon’s song, it’s like haunting and other-worldly, yet beautiful. Though I’m a life-long midwesterner, I don’t think I ever heard a loon here in Illinois. I became acquainted with them in...
