So you have a clean amp you just adore and you want to drive it, what do you do? You get the BOSS ST-2 Power Stack. Three main distortion/overdrive sounds (and endless in between options) will get your drive sound as you want it. When setting the 'Sound' control to 'Crunch' you will get a slightly driven amp sound and the more you dial the control clockwise the more distorted your sound will get. The BOSS ST-2 feels very organic and we really think it is a great pedal effect.
