Made in Japan and built like a tank, this is the true Old School, Swedish Death Metal pedal, requested by fans of the genre for years.
The sound profile on Standard Mode is identical to the original pedal (when cranked on max), and the Custom mode just sounds a little bit more boosted to my ear, with fatter low end. Two things to consider though when using this pedal:
i) ALWAYS use a noise gate along with it, the pedal produces insane amounts of gain, especially paired with HHs made for extreme metal (tested on SD Nazgul passives), it's very noisy without one
ii) For my pet owner friends, your cat will hate you using this, there's some frequency produced that makes them run amok, unlike my normal amp sound . .
