I recently bought a used 90s polychorus pedal off eBay. I’ve already had to replace the adapter it came with and replaced it with one from an old router it turns on but the effects won’t work can anyone help?
First off, did you check the polarity, voltage & mA of the router supply? And secondly do you have any experience with electronics at all? If so do you have a multimeter you can test the voltages with and if not it might be better to send it to someone for repair.
