Description

A compact, convenient and affordable version of the classic Mu-Tron III™ envelope filter

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.

    So when one of my favorite pedals, a mint vintage early model all-original battery-only Musitronics Mu-Tron III, recently started emitting a high-pitched whine (sure sign of a bad cap), I nearly cried and then hustled it off to Lingenberg Sound and started wondering if it was time to check out the newest version of this most classic of pedals.

    For my money, the quintessential Mu-Tron III sound is just dripping from Garcia’s guitar on the 5-5-78 Estimated Prophet. That is THE sound I’m looking for out of this pedal, and when my Micro-Tron IV showed up I set out to see if I could dial it in for that special tone. I just used what I had quick at hand: a G&L ASAT Deluxe, a late-90’s TS9 Tube Screamer with a JRC4558D mod, and a UAD Apollo Twin. Simple and straightforward, nothing fancy. But to be sure the Micro-Tron delivered.

    One of the great things about Jerry’s Mu-Tron technique is that he can trigger it at every fret position. This requires a boost (along with some careful playing technique). For my test, I ran the ASAT with the volume backed off a little (bridge pickup with the coil-split engaged for more of a single-coil sound, but the tone rolled back pretty hard to take some of the bite off) into the TS9 (Drive at 0, Tone at 7, Level at 9). This was run into the Micro-Tron IV in Up position and set to Mode LP, Lo Range, Level at about 8+, Peak at about 8-, Gain at about 7. This fed the Hi-Z input on the Apollo running a clean boosted amp in the UAD Console software. For good measure I threw some light compression and light reverb on with UAD plug-ins. That’s it. This signal was run through the UAD platform on a Mac and out my AKG K-240DF headphones while I listened to my signal on top of the 5-5-78 Estimated Prophet simply playing off YouTube.

    I’m glad to report that yes, 100%, absolutely that phenomenal Garcia Mu-Tron III tone from 1978 can be achieved with the Micro-Tron IV if you boost it and take a little time to dial it in. When I get my Mu-Tron III back from Lingenberg I’ll give the IV a real head-to-head shoot out on some real amps with some more guitars (and maybe compare the red and blue mod cards with the stock card), but I’m extremely happy that this pedal delivers as advertised with minimal fuss.
