DBX 131, single rack space 1/3 octave, 31 band mono EQ. Like new, works perfect. Balanced/ LoZ, 3 pin XLR and 1/4 inch TRS or regular 1/4 ins and outputs. Front panel EQ bypass. Switchable Boost / Cut 6dB or 12 dB front panel +/-12 dB Input Gain Range Internal transformer, no "wall wart". If this post is up, I still have it. No trades, please, cash only. Thanks for looking.
