It took me a while to recall where this item came from, and a wee bit of time to locate the matching cable. It was from a second hand Bass amp my band were using, sadly it didn't stand up to SIDCA levels of bass abuse. The amp died in a massive huff, smoke curling out it's back. The foot switch works fine- I just tested it on my old Laney amp- triggers drive on and off and pings off the reverb setting. I've also discovered another footswitch, which I will list also.
Any questions feel free to send me a message.
