huendeskes Century SGE-9B Bass Equalizer (this is a Boss GE7-B clone, Taiwanese made from the 90s)It's old, the pots crackle when you move them, but you don't usually do that while playing :) and if you clean them, they won't anymore, and it does its job. It doesn't eat or color the sound. Postage is paid by the buyer.
