The MultiDrive is considered an overdrive, more than a distortion pedal. The mode switch selects Tubeism, Standard or Flat overdrive type sounds. All with a preserved bottom since the pedal let through the low frequencies untouched and solid. With guitar, it provides a slightly overdriven bluesy tone with lots of sustain and body. This is the pedal to spice up your sustain! The MultiDrive was first introduced in 2001. The 2008 edition improvements added 3 dB higher headroom, higher sensitivity and new analog circuitry with higher dynamics and lower noise, as well as true bypass switching technique. 2015 introduces the Studio Edition with a complete new design, optimized signal path, new signal relay switching technique, overvoltage protection up to 18V and the possibility to power the pedal with anything from 9-12V DC. The new model is shipping from end of May 2015.
