Are you saying you use this stuff as the glue/transfer agent for Sunnyscopa film-free waterslide decals?

What I do - and this is very similar to a process @MichaelW described somewhere - is to use this MG Chemicals 4140A Flux Remover for PC Boards. I cut a small bit of old t-shirt (say 4x4 inches or so). I get that wet with the Flux Remover liquid. I then daub the PCB with the wet cloth, let it...

Great-looking build, and great write-up! Thanks for posting!

So I'm now pretty certain this new GW1-PRO just isn't ideal for pre-finished (i.e. powder coated) pedal enclosures. I finally tried this process last night with my new printer. I deliberately did not pre-wipe the enclosure with acetone before starting the process. The result: I got...

This looks great! Ever since I built two Byzantiums, I've been a huge fan of this circuit. It's been a near-constant mainstay on my board. As I mentioned in that build report, I took a lot away from How To Get 6 Modulation Effects From a Basic Flanger Pedal Like The Boss BF-2 by Michael...

During covid, for the brief time I got to work from home, I bought a remanufactured Steelcase Leap v2 from Crandall Office Furniture. Back in 2020 it came in at just under $500, even with a couple upgrades. Looks like they've since gone up considerably in price, but should still be quite a bit...

That's what surprised me, I am indeed using the Bouni KiCad JLCPCB Tools. There is a setting for Don't fill zones, but I don't have that checked. Somehow I managed to skirt past the auto-fill. Oh well!

I've made that mistake before (submitted Gerbers with zones not filled properly), so ever since I refill zones like it's my job. But you're exactly right, I somehow managed to generate those Gerbers with non-refilled zones. I actually loaded up the same gerber zip file I sent to JLC directly...

So tonight I finished up a pedal based on a PCB of my own design. And when I powered it on... nothing! After some debugging, I found that one of the signal nets was shorted to ground. I narrowed it down to what I assumed were three possibly bad components. Fortunately, this part of the...

@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...
