ok guys. I am a huge fan of Fortin pedals (and amps). As you might know i own a Randall RD amp which is been designed by Mike Fortin, a Fortin Zuul noise gate, and a Fortin Grind booster. I used to own a 33 Meshuggah signature Fortin booster as well, but i sold it for double the price i purchased it which founded me the zuul and grind together... The Zuul is the best noise gate on the market. Period. The 33 and Grind pedals are extremely good booster pedals to tighten up your sound. BUT(!) since i got an old Boss HM-3 (Hyper metal, not the hm-2 Heavy metal!!!) pedal, i have to say it can get really close to these boosters. The active bass and high tone controls on the HM-3 can provide the same tightness as the Fortin pedals, plus it is adjustable, not fixed like on the fortin ones... Although there is tons of bass in this pedal. the level at max might not give you the same amount of boost, but it is really close, and it is just enough to use on the OD channel of an already gainy amp as a booster. The dist could be at zero, but even then adds a bit of that fuzz and grit, which reminds me to the famous Swedish tone (HM-2), but it is not as fuzzy; more articulate, cut through the mix etc. It is between the hm-2 heavy metal and mt-2 metal zone. This pedal is awesome as a booster on the dist/od channel of a gainy amp. On its own it sounds shit.... P.S.: I still love my HM-2 pedal as well, but the HM-2 is way to fuzzy, messy etc. This HM-3 is more modern and fits more into the band mix. I am already looking the schematics to try a few mods. For example: -add an amp channel switching output like on the Fortin grind/33 pedals; -add more volume boost option; -add a switch which eliminates the distortion/clipping diodes entirely (convertng it to a booster) -add additional tweaking option as this pedal got tons of Bass on touch.
