I have a Boss DS1 for trade or sell. 25 bucks. I could probably ship to Canada. Dont know about UK.
Been used once just to see if it works. I'll include the box and the manuals, but i dont have the power supply. Also i can throw in a free 5 foot cable. Well, its around 5 feet.

Also, I need a Boss PS5 Super Shifter. I'll pay around 100 - 120 for it.
