The Friedman Dirty Shirley pedal delivers the sound of the full tube amplifier of the same name from the noble forge of Dave Friedman, but packs it in a pedalboard-friendly format. Accordingly, the pedal delivers an astonishingly wide range of sounds, from a subtle crunch for traditional blues to a lush overdrive for classic rock. The pedal convinces with a particularly sensitive dynamic that puts control over expression and sound shaping in the hands of the guitarist. In addition, the classic 3-band tone stack and the side-mounted tight switch provide precise means for adjusting the sound.
I’ve tried SO many overdrives and I started to think overdrives were simply not for me. The Dirty Shirley changed that and is actually the only overdrive pedal I want to keep on my board. Has quite a bit of gain too but I got it for medium gain, so can do way more than I need it to.
