huendeskes Century SGE-9B Bass Equalizer (this is a Boss GE7-B clone, made in Taiwan in the 90s) It's old, the pots crackle if you move them, but you don't usually do that while playing:) and if you clean it, it won't crackle, and it still does its job. It doesn't eat the sound, doesn't color it. 7000Huf+postage
