The Micro-Tron IV is a reincarnation of the classic Mu-Tron III envelope filter. The Micro-Tron IV provides all the classic Jerry tone and Bootsy funk, in a pedalboard-friendly size and powered by industry-standard 9V DC. Mu-Tron also added an OUTPUT level control and the ability to footswitch select between UP and DOWN drives. It's never been easier to cruise down "Shakedown Street" or get to "Higher Ground" – the Micro-Tron IV sounds amazing on guitar, bass, keys, horns, harmonica… you name it!

The Micro-Tron IV is based upon the award winning Micro-Tron III and improves it with Mu-Tron's very own MU Opto-Mod technology. They have also added standard CV input to accept an expression pedal such as the Dunlop DVP4 without modification! Furthermore, you can send envelope Control Voltage to other units such as the Phasor III and Bi-Phase pedals.


  • Three Filter Modes - Lowpass, Bandpass, Highpass
  • Two Ranges - LO & HI
  • Level, Peak & Gain Controls
  • On/Off Footswitch to Engage/Disengage the Envelope Filter Effect
  • Up/Down Footswitch for an "Auto-Wah" or "Down Swoop" Sound
  • Runs on 9V DC Power Supply (Not Included)

A nice modern upgrade to a classic pedal


I am a huge Grateful Dead fan - thus, this pedal was "required" I have the older version of the pedal that required a unique power adapter and was very large (not pedal board friendly). The IV version sounds great and is a lot more pedal board friendly - thumbs up to Mu-Tron folks for the update!
