Thing (I think) I've learned: Tastes change – always keep your pedals.
I've found that I've ended up trying pedals, not connecting with them, and selling them on, only to buy them again some time later.
Obviously there are some dogs out there that can and should be shifted. But if I run across a a decent sounding _________ (compressor, phase shifter, whatever) I'm inclined to keep it around now, even if it doesn't immediately find a spot on the pedalboard.
Sure, I've got four overdive pedals, two chorus pedals, and four others that mostly live in a box, at least for now. But hey, they're pretty small.
Thoughts?
