Meshuggah's legendary guitarist Fredrik Thordendal's signature 33 pedal will transform any gain amp into a brutal, destructive metal sound! Within the Fortin brand, this pedal is famous for its pursuit of the best metal tones imaginable. We put all our energy into developing the best modern guitar tones that an artist like Fredrik could be proud to put his name to. The result, after countless hours of research, design, development, prototyping, sampling, planning, reviewing, manufacturing, and endless tweaking, is the Fredrik Thordendal Signature 33 pedal! The boost level control provides a maximum of +22dB of level, and the side remote 1/4" jack for the amplifier channel switch adds a mini slide switch that can be switched to normally open or closed. ■Control BYPASS: True bypass footswitch LEVEL: Turning this up will drive the front end of your amp harder. The more you turn it up, the more tone you'll get out of your amp. Once you've got your amp responding the way you want it, don't be afraid to tweak the amp controls; hidden frequencies and harmonics may start to emerge.Power: DC 9-12V center pin negative external adapter/power supply only.
