20 band Realistic equalizer

This is, in my mind, the best equalizer Realistic ever offered. It has independently adjustable 10 frequency bands per channel and also has “zero gain” controls with optimizing lights - you can perfectly fine tune your speakers to your room, even if the environment differs between right and left! It’s just been completely refurbished & calibrated by a well known local tech and is working as new; I’m now using this Soundcraft preamp with a built in eq, so no longer need an outboard unit.
