Bring out yer Diptrace

Hmm, maybe we should refer to it from this point forward as the Pastel Preamp?... just to be on the safe side.

Nice guess by the way.

'Twas NO guess...



'Twere an EDJAMACATED guess...

I knew I'd seen that Kliché-like layout with a switch somewheres, and I did hunt it down methodically, like it were a hidden solder-bridge under an IC socket ... I perused the "IN PROGRESS" Wish-List entries ... and there it were... the Pastel Pre preening away with its panties down...

Whatever you call em they sure are delicious

OK.... first prototype is done, time for a break.

Not only was that super fast, it looks fantastic.

That’s insane!

All of us in here posting our cute layouts and then the grandmaster comes in and flexes

Gonna redo this one completely (traces are a fucking nightmare with this layout) but wanted to make sure it could all theoretically fit. Might replace the >1µ film caps with electros but I'm never confident about the polarity when doing so. It's the Trans-Boost, as hyped recently by @Feral Feline

"Hyped" is somewhat strong, but I'll take it (the PCB).

a switchable board for devi ever's aenima / torn's peaker and US circuits. (guess who just watched a king gizzard rig rundown)

Another multiconfig devi ever board. Happy thanksgiving!

Wondering if I can get a sanity check on my Jawari layout. The Jawari is a sitar-like Escobedo circuit fragment (towards bottom of the page here). He seems to use somewhat different conventions than I'm used to - perhaps these were more common in 2000 or so?! The in/out labels and footswitch are somewhat idiosyncratic, and the power section is missing a reverse polarity protection diode. I tacked on a volume control at the end of the circuit as well, but I'm wondering whether it's better as I have it, or perhaps as a single A250K pot without the R3 resistor.

I hadn't done a J201 layout - I think I got DSG right for the Aion adapters (or for other JFETs like 2N5457, although I understand the sound might be somewhat different).

I've also never had a build with a transformer (have my first PPCB transformer boards in my Black Friday order), so not sure if extra care needs to be taken in routing near them.

Thanks!

The way you implemented the volume control is exactly how Moonn did it.

Everything else looks good as far as I can tell!

@rwl Can't help you with the transformer question, because I haven't used them either.

+1 for the symmetry on your layout. Nice, clean placement.

I have used J201s, which are mainly available in SMD format now and aren't particularly difficult to solder. It might be cheaper and more future-proof to use a combined footprint that allows you to mount the SMD component on the same board and that way you can roll with whatever you have access to without relying on additional adapters. Just a thought. There's room to put the SMD footprint to the left of the through-hole component and you'd probably end up with +2 symmetry as a result

I think I need to create one of the hybrid SMD/through hole footprints... I'll give that a shot before getting this fabricated.

@finebyfine thanks for taking a look as well. I did look at the Moonn schematic but also found parts of that to be confusing!

Definitely worth doing. If I was better about it, I’d even use SMD hybrid footprints for BJT transistors

It's done - just sent this for fabrication . Thanks to both of you for taking a look!

Your layouts are improving, looking good!

One small suggestion... you may want to consider increasing the font size, particularly on your control labels, diode values, and anything similar in size/weight. It's likely that this is a bit smaller than the PCB fab can legibly silkscreen.

gkrails from talkbass minus the boost footswitch. I'm procrastinating work stuff and it's been a blessing for my pcb output

Non guitar pedal related double post. Maybe the silliest thing I'll ever make.

Spoiler: slightly explained

We have some random equipment at work that is easier to use with sd cards than cables and keeping one loose in my pocket always makes me think it's a guitar pick and therefore something that can just get flung across the room when I take off my pants. Every storage thing I could find was for like, 10 cards, and I just use one at work. Uses a 50 cent smd connector.

How violently are you taking off your pants?
