The Friedman Dirty Shirley head has been a favourite amongst rock guitarists, known for its versatility and being on of the most touch sensitive single channel amplifiers, you can now have the best parts of the amp in a compact pedal format. Full band EQ allows lots of tone shaping and the side mounted tight switch helps clean up your low end. With the volume and gain controls you have tons of headroom to work with and the gain control really responds to your guitar volume adding even more versatility to the pedal.
