For sale: Empress's legendary "Para EQ." This pedal is excellent not only as an equalizer but also as a clean booster. There are basically no operational issues, but from the time of purchase, a brief crackling sound occurs when boosting from 0dB. (Other than that, there is no crackling.) Can be used with both guitar and bass. If it doesn't sell at this price, I will continue to use it myself, so I am not considering lowering the price. No box included.
