For sale is a DBX 215 Graphic Equalizer. You can use it as 2 channels with 15 bands of EQ or one channel with 31 bands of EQ. It's in excellent condition, as it's barely ever been used. It's been sitting in the box pretty much since I've had it. I just never got around to using it. I plugged it in turned it on and everything lights up as you can see in the pictures.
