This absolutely stomps. You get a thick, juicy, harmonically rich and dynamically responsive tone that instantly channels Angus, Jimi and all those other proponents of the classic Plexi tone. The right hand side offers a boost, as many others do, but it also offers a fuzz. The fuzz is thick, juicy, fluffy and warm... delicious. This is perfect as an 'always on' preamp style pedal or an instant hit overdrive. Very good indeed.
