Zipper MKII

Optical Compressor

The first thought that comes to mind when listening to the phrase optical compressor is no other than the old and unique Urei® LA3A®! Our goal was to create an optical compressor with such simplicity, capabilities and warmth but at a compact size, asd the result is the Zipper!

The Zipper MKII is a discreet and quiet optical compressor with tons of headroom and punch to your sound without changing your tonal character.

The hand-selected optical element provides auto adjustable Attack and Release, depending on the signal’s strength and amplitude. Select between Hard and Soft ratio from a dedicated toggle switch, Hard being 10:1 and Soft being 4:1 compression ratio.

Can be used as a maximazer or clean booster with the compress control up to 9 o’clock.

At high compress settings the sound becomes punchy and percussive perfect for “Gilmourish” licks, funk and chicken picking styles.

A high end Pro-Audio compressor at your feet!
