  1. Hello again everyone,

    My front end effects are currently


    is there any point getting a compressor as well or would this be a waste of money.

    I understand that a compressor boosts lower signals and limits higher signals and hence increases sustain but would it be a waste of pedal board space?

    I mostly play a kind of muse/mars volta kind of rock.

    A limiter is simply a compressor with a very high compression ratio... generally a 20:1 ratio or higher. Once a certain voltage is reached, it limits it from getting any higher. A compression pedal with a lower ratio setting would be useful for evening out your volume level. After a certain threshold is reached, the signal increases at a slower ratio (i.e. 4:1) than normal (1:1). Try one out and see if you like how it sounds. You might want to try some dual band compressors as well... you can set a crossover point and compress the bass and highs at varying degrees.

    The graphs attached below will show:

    LIMITER - once the voltage in reaches the threshold, the voltage out no longer increases

    COMPRESSOR - once the voltage in reaches the threshold, the voltage out increases at a slower rate

    A limiter is a compressor set at an extreme setting...

    ie: a limiter would have a ratio setting of say 20:1... for every 20 units the signal goes over the threshold level the pedal would only output 1 unit over the threshold, giving a big squash to the signal and protecting the amp(s) from clipping. Normaly a limiters threshold level would be set just below the point of clipping.

    Compressors are usualy set with a ratio of between 2:1 and 6:1, meaning for every 6 units the signal goes over the threshold the pedal only outputs 1. This doesnt give the sound as much of a squashed feel and would even out the spikes in level in your playing. The threshold on a compressor would be set just below your highest level when playing to make it sound quieter and more even. The gain makeup would then be turned up to give the impresion that the quiet notes are louder.

    If I could draw I could make it so much simpler :)
    There are plenty of help places around the net on compression, just type it into google... it makes a lot more sense with some graphs :)

    so some people have told me a limiter can prevent a speaker from blowing when your slaping at high volumes is this the same for a compressor??

    thanks for your explanations, ive also always wondered ohw they worked

    any chance you could explain it in terms of sound waves?
