Changes

''Boosts'' (also sometimes called ''Overdrives'') are pedals used to boost the signal strength or fine-tune the signal frequency response to get more distortion and/or a preferable distortion tone from a distortion stage, typically an amplifier's pre-amp. They typically cut bass or boost treble to get more distortion from the midrange and highs while leaving the bass less distorted. This gets a "tighter", less "muddy" tone.
