The NEW Micro-Tron IV is the newest 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. We’ve 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 new Micro-Tron IV is based upon the award winning Micro-Tron III and improves it with our very own MU Opto-Mod technology. We 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.
