Moving pedals as a single lot is going to be hard unless you have a collection of valuable pedals that might interest a dealer, full time flipper, or serious collector. IMO your best bet would be to list the ones actually worth something individually and give away or just toss the rest. Shipping has gotten expensive and pretty much destroyed the cheap pedal market.
The earlier suggestion to list your stuff in the TB classifieds is a good one. There’s no sales commission or listing fee. Just put them all in one big ad with individual prices for each item like others here have done. Anything that’s going to move will sell relatively quickly. After that you can decide what you want to do with the rest of your collection.
Luck!
