I'm an old school Swedish death metal (Entombed/Dismember/Bloodbath) fan and I must say this pedal is an exact copy of the BOSS HM-2, which is such a rare pedal to find!If you're looking for that aggressive buzzsaw tone but don't have the finance to get an HM-2, this a really good option! However, use it with caution and keep it like your dearest stuff ever, since it has a plastic body and might break or get damaged easily if force is applied upon it!And if possible keep 2-3 pieces with you, since you really can't rely on it..but one should work fine!I have been relying on that single pedal since quite sometime and frankly I think i can rely on that single pedal itself so didnt buy any more!P.S. I would recommend you guys to get and boost the signal of this pedal or the HM-2 with pedals like BOSS SD-1 or IBANEZ TUBE SCREAMER in order to really power up the buzzsaw tone!
