The Micro-Tron III provides all the classic Jerry tone and Bootsy funk, in a pedalboard-friendly size and powered by industry-standard 9V DC. Mu-Tron has 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 III sounds amazing on guitar, bass, keys, horns, harmonica… you name it!
Optical Envelope Filter based on legendary Mu-Tron III circuit
The Mu-Tron III has become a legend because of the smooth and funky sounds it has produced on countless hits. Not all envelope filters are created equal and the optical design of the Mu-Tron has stood the test of time. The Micro-Tron III is based on the original circuit of the original and has already become the new gold-standard.
Pedalboard-Friendly compact 9V DC design
Unlike the vintage Mu-Tron, the Micro-Tron III does not need to be plugged into the wall, nor does it take up half of your pedalboard. The Micro-Tron employs the same circuit as the Mu-Tron but is powered by our patented "Medical-Grade" power rail internally and not a clunky transformer. It only draws 52 mA and will work with any 9V DC center negative power brick or one spot or boss adapter. We even designed a 9V portable battery pack called the PS-2 Battery Buddy that will power many 9V pedals and your 5V mobile devices as well.
Up and Down modes accessible by foot switch and expression pedal for even more control
Now you can go between "UP" and "DOWN" modes with the tap of the auxiliary foot switch and even fine tune the gain with the use of the external expression pedal (not included).
- LP (lowpass filter) passes all the signals below the peak and attenuates signals above the peak
- BP (bandpass filter) passes signals only near the peak and attenuates signals below and above the peak
- HP (highpass filter) passes all signals above the peak and attenuates signals below the peak
- LO sets the filter sweep to a low range for most rhythm guitar, bass and lower fret uses
- HI sets the filter sweep to a high range for accenting string harmonics or for up-the-neck and solo work
- LEVEL controls the ouput volume of the effected signal
- PEAK (or Q) controls the filter audio response from very weak to very strong
- GAIN controls the envelope and filter audio drive
- ON/OFF Footswitch engages or disengages the envelope filter effect
- UP/DOWN Footswitch
- UP position produces familiar “auto-wah” sound – like a heel-to-toe sweep on a wah pedal
- DOWN position produces a “down swoop” sound – like a toe-to-heel sweep on a wah pedal
