The idea and the execution is seriously innovative and impressive. (After troubleshooting a local issue with a failing USB microphone I can verify that the live mode works great. This is the real deal.) Don't miss the photos of the physical setup from the gallery features to the right of the pedal detail pages; excerpt: https://im.static-thomann.de/pics/images/stompenberg/backsta... https://im.static-thomann.de/pics/…

It's a inhouse design with a PCM3060 as audio codec.

Hats off to those who came up with this and convinced their superiors that it's worth trying. Most pedal demos don't give a very good idea how something will sound with your setup, because well, they're using their own, filtered through speakers and microphones at that.

You can turn off the speaker simulation + route your own setup in the "live" mode. I gave it a quick try and seems to work quite well, although the latency is quite annoying. But it's a demo, not performance tool after all.

They are self hosted in southern Germany and you connect via WebRTC, so if you are far away from there it will have additional latency, sorry no way around it.

I have so many questions as to how they're handling controlling knob changes! From the pictures it looks like they've yanked the pots out and hooked the boards up to their rig, which raises more questions. This is something I've tried myself, and it's not trivial. Digipots won't work in the signal path and are noisy and imprecise, so companies that do this (there are very few!) like Chase Bliss use vactrols. Using th…

This is the only snippet of information I could find about it. Seems indeed like noise and imprecision would be issues even if replacing the knobs and switches, the imprecision you could live with as it's a demo, but the noise certainly is not wanted.

> The first step is to dismantle them, measure the potentiometers and replace them with digital potentiometers and switches.

Most of them are controlled with Digipots, but yeah indeed it was not easy to get it working for all the different setups.

I'm in Spain so probably closer than most others here on HN, the latency is really not that bad. Seems you're related to Thomann/Stompenberg, so just wanted to thank you for this service! Will certainly help me in finding pedals without having to go through the buy/sell process I'm currently doing.

Did you run into noise issues? I actually haven't tried a digipot in a signal path (they do work great for other controls like LFOs and the delay time on a PT2399), but everything I've read online has told me to avoid it. I'm not hearing any in the demos so clearly it's workable!

After doing my research: Thomann is a very large reseller (1700 employees according to wikipedia) in musical equipment.

What's the story behind how a reseller got into designing custom raspberry pi add-on boards to demo third party pedals online?

According to their blog posts it was a contract work by another company: https://feinarbyte.de/projekte/stompenberg/ (german site)
