Boost pedals raise signal level, add gain, or do both. A clean boost leaves most of the source voice alone and pushes the next stage harder; a coloured boost changes the frequency balance as it lifts the level, while a treble or mid boost can deliberately narrow the emphasis. Controls such as gain, output, tone, presence and headroom determine whether the pedal behaves as an always-on preamp or a solo lift. Placement matters: before an overdrive it increases clipping, after it mainly increases level, and into a clean amp it may simply make the rig louder.
Connects input directly to output through mechanical or relay switching when the effect is off, removing the active circuit from the audio path. It avoids buffer colour but leaves cable capacitance and switching design to influence high-frequency loss and possible switching noise.
