The Marshall ED-1 THE COMPRESSOR Guitar Effect Pedal, Compressor /

Sustainer. Modify the sustain and attack of your guitar sound.

The Marshall ED-1 THE COMPRESSOR lets you take control of your

dynamics. Compression is perhaps one of the most useful and versatile

effects available to any guitarist who is interested in improving their

tone. The purpose of the Compressor pedal is primarily to allow you to

modify the sustain and attack of your guitar sound. Using classic

variable gain techniques the Compressor will provide masses of clean

sustain, which you can utilise whatever your style. The Compressor

pedal senses the level of the incoming guitar signal and, as the signal

level decays, the gain of the internal circuitry is boosted to provide

extra level and hence sustain. The attack control modifies the dynamic

response of the guitar signal (the effect of plucking a string) and

allows you to achieve a range of effects from rounded and mellow to

percussive and funky. The Compressor also features an Emphasis control

which allows you to assign compression and target the frequencies you

want to compress. This means that you can, for example, tighten up or

compress your bass notes and let your treble notes ring out.
