The new Walrus Audio Mira Optical Compressor is the latest pedal and features what they are calling warm analogue compression. It has plenty of sustain along with a smooth attack and release, which can be blended in with your dry signal.

This Walrus Audio Mira Optical Compressor offers musicians a warm, smooth compression based on an analogue optical circuit. It comes pretty feature-packed and is perfect for both guitar and bass. The true bypass optical compressor offers players a studio-grade compression circuit in a handy compact pedal format, making it perfect for taming your frequencies and adding some punch when required.

Studio-Grade Compression in a pedal


With traditional compression controls including, Level, Threshold, Attack, Release, Ratio and Make-Up (Gain) along with a Blend knob for adding in your dry signal. This latter control allows you to maintain your playing dynamics and note clarity, whilst mixing in your compressed tone.

High Pass Filter

It also has a push-button High Pass Filter for the side-chain. This can then be used to prevent bass frequencies 120Hz or below from engaging the compressor as much as the higher frequencies. This will then stop the compressor from overworking on any lower notes.  Making it great for bass guitar and for any low-frequency dynamics for guitar players.


Overall, this does look like a fully-fledged studio-grade compressor in a pedal. Sure there is no metering, but to be honest that would be awkward to see anyway. Therefore, I’d be more than happy to use an optical compressor like this on my pedalboard setup. It comes across as an ‘always on’ style of effect and could be the solution for anyone looking to get a consistent level from their rig.

MSRP – USD 249
