Are you a DIY enthusiast?
We have a ton of boards full of parts that we scavenge parts from. If you don't mind a little work we have scavengable boards full of parts. Tact switches, leds, components, XLR jacks, Midi jacks, 1/4 jacks. Basically all the stuff you want, cheap.
What's the catch?
These are all from dead gear. Somewhere on these boards there is a problem. But as you are buying them just for parts to make something totally different, it's not an issue. Please do not buy these boards for replacing them in the product it was meant.
