From the vendor
Fortin is famous for seeking out only the best metal sounds imaginable. Fortin 33 is an effect worthy of Fredrik Thordendal, Meshuggah guitarist, proudly signing it with his name. It's a real detonator, offering gain up to +22 dB and transforming any amplifier into a metal machine of destruction. True bypass. Power supply: regulated mains adapter 9 VDC. The dimensions of the main PCB 50 x 50 mm. The dimensions of the True bypass PCB 50 x 42 mm. Enclosure type: Hammond 1590B.
