Description

The Boss CS-2 Compression Sustainer is a smooth, responsive compressor pedal with transparent tone and sustain enhancement. Its Attack and Sustain knobs provide intuitive control of compression character and amount. The CS-2 has been a studio and live favorite for adding glue, sustain, and smooth dynamics to clean and overdriven tones.

The Keeley Compressor Mini is a compact, streamlined version of Keeley's acclaimed studio-quality compressor, delivering smooth, transparent compression in a small pedalboard footprint. It evens out picking dynamics and adds sustain without obvious pumping or tone coloration, keeping both single-coil and humbucker tones natural. Favored for clean funk strumming, country chicken-pickin, and always-on tone enhancement, it offers fast, simple dial-in by trading deep control for ease of use and minimal board space. It runs true bypass and is a popular grab-and-go option for players who want the classic Keeley compression character without the larger multi-knob enclosure. Its low noise floor and natural feel make it a dependable front-of-board utility.
