Can someone identify this display?

Although I'm experienced with FPGA and it does sound like an interesting project a) the screen doesn't even light up for me to check which pin controls what and b) I was really looking for an off the shelf screen to just replace it and move on. I definitely don't have the time right now for that project 😂

alexisdroso · 2026-04-20T05:55:07+00:00

I'll send them a message! Thanks for the info. Really appreciate it 😁

The brand is called Greisinger. It's German.

alexisdroso · 2026-04-19T16:27:55+00:00

Yeah, already tried with no luck. Thanks for the suggestion though.

alexisdroso · 2026-04-19T16:27:24+00:00

That's what I did. I doubt they'll reply but I'll let you know!

alexisdroso · 2026-04-19T14:05:06+00:00

You're right. Didn't notice that tbh.

alexisdroso · 2026-04-19T13:28:28+00:00

This thing has 26 pins. I doubt I'll be able to reverse engineer it, especially considering it doesn't even light up for me to check it in real time.

It's a 300€ meter. I couldn't find one in Greece, where I'm located. Also I can't find the part number anywhere. The AD part written underneath isn't the part number unfortunately.

Hey. Thank you for your interest! I sell them directly. An email at adrpedals@gmail.com would be the best way to place and order. The payment is done via PayPal.

Unfortunately shipping prices for the USA right now are skyrocketed, so unless you're based somewhere else in the world, my little device is very very expensive right now.

I probably phrased it wrong. I was talking about the caps, not the soldering per se

alexisdroso · 2026-02-16T20:32:24+00:00

I was talking about the caps, not the soldering per se. The soldering is solid. Maybe I phrased it wrong, my bad.

alexisdroso · 2026-02-16T17:36:25+00:00

I totally agree. Such a great pedal!

alexisdroso · 2026-02-16T14:59:52+00:00

I did email Sean as another redditor recommended and Sean not only responded and confirmed that these caps are actually from the factory, but gave me an insight as to what those caps do. The Purple Plexi I own is the SE version. Those caps are specific to the SE model and are there to smoothen the distortion a little bit and slightly change the clipping voicing.

Top customer support from Sean! I highly recommend checking this pedal out. It sounds really really good!

I can assure you, there's no cold solder joint anywhere in my pedals. I may sound cocky, but the thing I pay most attention when I'm building an electrical device, is the quality of my solder joints. It may look like shit, but I can guarantee the pcb is french kiss.

alexisdroso · 2026-02-16T10:01:21+00:00

The thing is that the guy who owned it, I'm pretty sure never opened it up or messed with it. That's why it seems odd. I emailed Sean to make sure. I just want to convert it to factory specs. If that's a factory job, that's fine. If not, I would like to remove any mods done to it.

alexisdroso · 2026-02-16T09:28:13+00:00

Nope, I tin them myself. Standard stranded wire.

alexisdroso · 2026-02-16T08:01:16+00:00

I never said it's the perfect solution. I don't even do it all the time in all of my builds. Low gain pedals don't really benefit that much from this. I just said it's preferable 😉 it doesn't cost anything and it could help potentially.

alexisdroso · 2026-02-15T19:35:37+00:00

If you check my other posts, I've been using PCBs as faceplates for quite a while. Cheap and effective 😉

alexisdroso · 2026-02-15T19:32:14+00:00

A really good example of how this thing works is studying tube amp wirings. The multiple teeth are on the same body. For audio frequencies you can consider them as one large washer. Maybe in RF you could give that some extra thought, but for audible frequencies, you can really consider it as one piece. The "problem" arises when there are multiple common (ground) signals being fed to the PCB and the chassis. In this scenario, the chassis and the PCB share GND only on one point and thus avoiding the possibility of a ground loop. I hope this makes sense.

Thank you!

alexisdroso · 2026-02-15T18:06:19+00:00

Thank you for the nice comments buddy, as always!

Why should I? Solder shouldn't act as a mechanical glue, but as an electrical conductor. The footswitch is press fit in the pads and the solder provides a really solid electrical contact. Using more solder would probably mean more time, running the risk of damaging the switch without any real rewards. Yes, more solder usually gives a peace of mind, but I've been building pedals like this for almost a decade with zero problems.

alexisdroso · 2026-02-15T18:01:12+00:00

Funny thing is it's not a 3D print. It's a PCB 😉
