From Marshall, the ED-1 pedal has the standard knobs for
volume, attack, and compression, but also includes an emphasis
control for a more personalized sound.
Compression is perhaps one of the most useful FX available to
any guitarist who is interested in improving their sound. The
purpose of the Compressor pedal is primarily to allow you to modify
sustain and attack. Using classic variable gain techniques the
Compressor will provide masses of clean sustain, which can enhance
any playing 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, 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 chord sustain to muted,
percussive funk lines.
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.

The ED is equipped with the usual controls for volume, attack
and compression, as well as an emphasis control, which can be used
to emphasise low or high frequency ranges, which in turn
counteracts the effects of higher compression and can be really
