Here for sale 2010s Buffalo FX Propeller boost guitar pedal. Great boost pedal with additional bass and treble controls. It's in very good condition and comes as pictured. The Propeller boost Circuit has been tuned to deliver anything from a flat transparent tone that lets the full glory of your amp shine through to rounded lows and a bell like top end chime that adds another dimension to your tone. Roll back the treble for a more vintage flavour or cut the bass and push it hard for a great solo boost without any low end muddiness.
