Martinic Colorsound Tremolo

The Martinic Colorsound Tremolo is a precise recreation of the famous effect pedal from 1974.  This virtual effect plugin aims to recreate the tremolo effects from two different iterations of the popular stomp box.

The Martinic Colorsound Tremolo AU/VST plugin, tested and authorized by Macaris, recreates the famous Colorsound Tremolo effect pedal used by Green Day, Joe Bonamassa, and Phil Manzanera among other well known guitar players.

Includes recreations of both the 1974 and 1996 version of the original pedal.

For a full list of features, check out the online manual.


In the 70’s, brothers Larry and Joe Macari of Sola Sound developed the Colorsound Tremolo, modeled after the tremolo of a VOX® AC30 tube amp, using only 4 transistors. You can read more about the history of the Colorsound Tremolo here.


Due to its immense success, you can still buy the hardware version from Macaris here.

Colorsound Tremolo Overview

The Martinic Colorsound Tremolo was created using our trademarked ACE modelling technique to bring precise recreations of both the 1974 and 1996 models into modern DAW applications. With the added capabilities of stereo and tempo sync, it’s the new “go to” tremolo effect plugin for achieving that sweet vintage vibe on any audio track!
