The classic 166 is an absolutely sick, classic comp that's able to smooth uneven levels, add sustain to guitars, fatten drums or tighten up yo' mixes. It has full sidechain capability. It's great for controlling stereo inputs such as stereo keyboard inputs but it also works as two independent mono units with separate controls for each channel.
This unit is lightly used and functions great. It's ready to ship out to you the next day
