sixtyfive is a vintage-style, RMS Compressor, inspired by the dbx 165A, a classic 1970s compressor found in many studios, but it also adds a couple of new twists.

It's a soft-knee RMS compressor with a vintage flavour. The RMS detection and soft-knee help to give a smooth and musical compression experience, the non-linear response imparts character and the gentle saturation brings colour and warmth. As well as all of the originals features, this version adds parallel compression, extended knob ranges and peak metering.

sixtyfive can deliver a range of compression from gentle smoothing of vocal performances to brutal slamming of your drum buss.
