I am curious about this pedal. Boss HM-3. I heard about it because the guitar player from Monolord uses a Boss FZ-2 Hyper fuzz and a Boss HM-3 Hyper Metal. I hadn't ever noticed the HM-3 Hyper Metal. It's tough to keep track of Boss's naming of pedals. But I absolutely love the FZ-2 so I am now curious about the HM-3. I havent found a DIY board of it yet. Anybody know of a pcb available? There is a vero layout on dirtboxlayouts that I may tackle if I cant find a PCB somewhere. Any of you guys played one of these HM-3's? are they as kick ass as the FZ-2? Demos dont sound great for the hm-3 but that doesnt mean anything. You should listen to this song tho.
