Keeley Electronics Pedals

A chorus pedal is a modulation effect. The original signal is split and run through a short delay and then combined with the original signal. The delayed part of the signal can then be modulated to create movement to create a thicker tone. A classic effect used on electric, acoustic and bass guitars.

In its simplist explanation a compressor makes the quiet parts of the signal louder and the louder parts quieter delivering a more consistant loudness. Can have the most subtle of effect through to the very obvious "snap". A compressor can also increase sustain and provide extra gain to push the front of your amp.

From mild soft clipping overdrives, to germanium based fuzz circuits, to all out hard clipping high gain, these pedals give you the drive to suit your taste.

A flanger pedal is a modulation effect. Essentially the same as chorus but with a shorter delay time and utilising delay feedback. The distinctive sound comes from modulating the delay time giving you the classic sweep sound.

Boost pedals allow you make your sound "bigger" by adding more gain to your signal before it hits the input on your amp. They're typically used to help a solo cut through or to obtain a natural overdrive from your amp.

A place for those pedals that don't quite fit in to any particular catagory.

Multi effects units combine all the common effects and some uncommon ones into one box usually with a range of switches allowing you for example to create different patches allowing you to go from a clean sound with chorus straight into a high gain lead patch with delay with the press of a button. Infinite sounds in a compact package, the swiss army knife of guitar effects.

Reverb pedals modify the signal in such a way that you can replicate playing in different sonic spaces. Delay pedals allow you to repeat your sound at pre-determined intervals after you've played it. Both effects whether used independently or together can add warmth and depth to your tone. Reverb and delay pedals are collectively known as time-based effects and are typically positioned at the end of your signal chain.

The oldest guitar effect. The first stand alone effects unit outside of reverb was tremolo produced back in 1948. The effect creates a rapid variation in volume of the output of your guitar, "Gimme Shelter" is the perfect explanation.

One of the classic guitar effects of all time. The pedal creates a vocal like sound by sweeping through the frequency range of your guitar. Most commonly controlled with the foot allowing you to work in real time and sequence the effect to what you are playing. Some pedals over an auto function allowing you to switch on and off a preset wah effect. Here you will also find envelope filters. This pedal reacts to how hard you play, play hard and you get a treble boost and as the signal drops the boost dies away, the ultimate funk tool.
