Awesome little tube screaming beast! This little fella is the miniature version of Keeley Pedals acclaimed Red Dirt Overdrive. Super easy to use and won't take up any room on your board. Set your desired level of gain, adjust the tone knob and boost selector to achieve your desired level of rocking goodness! You can really get some huge tone out of this little monster. Because of the addition of the JFET input buffer, the Red Dirt/Red Dirt Mini excels where many fail. You can drive to your hearts content but retain a more open and responsive sound.
