SM9Pro+ was developed based on the distortion core of Maxon SM9 Super Metal 9. Original SM9 was sold just after NWOBHM which created a big boom in the late 1970s.
SM9Pro+ creates scooped heavy metal tones with high-level gain circuitry and cut midrange circuitry. Wide range of setting from NWOBHM to current heavy rock / loud rock using drop D tuning is available with simple four control knobs.
Operating voltage 9V or 18V mode is switchable via an internal slide switch accessible through the units battery compartment. In new power-saving circuitry for SM9Pro+, DC to DC converter only operates at 18V mode. When 9V mode is selected, DC to DC converter does not operate, and SM9Pro+ operates with battery or AC adaptor directly. There is no power consumption for DC to DC converter, which makes battery life last longer.
SM9Pro+ has increased dynamic headroom with internal operating voltage set at 18V. Stable high-quality sound is available as unintentionally-generated distortion is significantly reduced.
True Bypass Switching using 4PDT mechanical switch lets your instruments signal pass through a non-electronic bypass line when the effect is disengaged. MADE IN JAPAN
