My clone of the” The HM-2 Heavy Metal” pedal, a legend for those who play Death Metal music, named “HM-424” in Eurorack format. Insane amount of boost and tone-shaping. The high and low EQ controls are +/-20dB peaking filters at ~88Hz and ~1000Hz. Swedish Death Metal Chainsaw Buzzsaw sound.
Thumb Screwer is based on the “Legendary” Tube Screamer (TS808/TS9) Great overdrive with mix piecing nice mids. Extra tone shaping functions like “Bass boost” and “Diode clipping – (Odd/Even)” settings added.
