The Golden Age Project Comp-3A is a remake of the classic UA LA3A levelling amplifier and compressor with a few extra little tricks up it's sleeve. The Comp-3A maintains the same features as the original - mono channel, half-rack unit with VU metering. The beauty of this compressor is it's simple design with a one knob "peak Reduction" knob to control the amount of gain reduction. The Comp 3A is an opto, or optical compressor. This style of compression is a nice, gentle for of compression - great on vocals and acoustic instruments. You also have the option to link two units together for stereo bus compression / limiting. Golden Age Project have done an impressive job emulating the classic originally released in 1969. Check out the video below for some live examples in action!
