Project Overview

We all know that the Keeley Compressor is the most acclaimed boutique compressor in the world. The reason is simple; the pedal can make an instrument sound like it’s been professionally recorded assuring you that whether you’re a beginner or a pro, it will take your sound to the next level.

Introduction

Keepressor is a compressor with an expander/sustainer. This means that besides acting as a regular compressor that limits the peaks in your playing, it also adds more and more gain as notes fade out, giving your notes life beyond their natural lifespan. Isn’t that great? A pedal that offers the right amount of sustain and expressive bloom your notes need.

Also, the four knobs version gives you lots of easy-to-reach compression options, so it won’t take you all day trying to find the perfect sound. Let’s check them:

Sustain: Sets the amount of sustain. A good starting point is at about 9 o’clock. At 12 o’clock, you will get a full sound that is a great fit for funk or lead playing, compressing the loudest notes and raising up softer ones. At 3-5 o’clock, you will get a singing sound that feeds back easily. The noise level rises slightly from 3 o’clock onwards.

Volume:  Sets output volume level.

Attack: this pedal has an Internal Attack control, designed for bass players with high-output active pickups or active pedal boards with buffers.

Clip: it also has an Input Sensitivity Control, meaning you can use this in your studio to run keyboards, drum machines, drum mics, even master recordings, and other line-level uses. You’ll raise your signal to a new level of sonic awesomeness.
