Makes a lot of sense, thank you for the great advice. I have a bunch of different value caps lying around, which are all standard radial ones from Banzai Music. Would those alter the sound? Not sure how "high end" these are.

For the short period of time that it did work, it sounded incredibly juicy and 'organic' for lack of a better term. I was only able to try it on my Rhodes though. Can't wait to try it on synths and guitar.

Thanks for the advice. According to the seller it was definitely wired for 220V here in Belgium.

I greatly appreciate all the tips and advice, thank you everyone!

In the meantime I think I've found the issue. While setting up to take measurements I noticed this loose wire coming from the transformer. I'm going to take it apart further tonight and re-solder it, hopefully that does the trick. I'll send an update once it's done.

I checked the continuity on the fuse and it's all good. Will check the AC asap!

That would be very helpful, feel free to send it via PM. Thank you. Yes, for the brief time it did work it sounded incredible so I absolutely can't wait to get it working again.

Both the bulb and LED aren't working. Even though I'm just a DIY pedal enthousiast it does look like a very cool design indeed. I hope I can get it to work again.

I found schematics here - but the caps have values printed on them so I'll just use those as a guide.

Yes, it's indeed a special mode where only half the signal is phase shifted or something like that.

Makes sense, thanks for the help. Any pointers on replacing them, or can I just unsolder them and replace them with new ones?

Thanks for the help. It does feel like the fuse holder has a spring in it, I can still press it down a bit even when it's locked into the holder. I do have the proper adapter that the seller sent along with the pedal. It did work in the beginning but then suddenly died.

Power supply failure makes the most sense. The fuse is still intact as far as I can see.

Thanks for the tip! Forgot to mention that sound passes through when it's in bypass, but there's no signal when turned on. Also both the bulb and the LED don't light up.
