The Electro Harmonix Bass Soul Food is a natural overdrive/clean boost for the tone conscious player and it enhances the original sound of an instrument and amp without sacrificing the original, core tone. Refinements for this new bass version include a gain stage, treble control and signal path that are optimised for bass guitar, and that work brilliantly for guitarists wanting extended low frequency response. And a new adjustable clean blend assures an articulate, full tone while the boosted power rails from the original deliver that heralded extended headroom. Selectable true or buffered bypass modes and a switchable -10dB pad for active instruments complete the package. Bass Soul Food runs on a 9V battery and ships with a EHX9.6DC-200 power supply.
