3Leaf Audio

The Mutron III envelope filter was a staple of 1970′s funk and soul music that shaped the sounds of Bootsy Collins, Stevie Wonder and Jerry Garcia among others. But as good as the Mutron sounded, it was not without its problems. It was huge and required a special power supply, and it had a sensitivity control that changed your volume when you kicked it on. Then there’s the price – originals routinely fetch $500 or more on eBay!

The new Proton envelope filter contains the essence of what made the old Mutron sound so good, without all of the drawbacks of the original. It’s small, it runs on a standard 9-18v DC power supply (no battery), and it won’t change your volume when you kick it on. But most importantly, it sounds FUNKY. With its simple control layout, you can easily dial in the slurpy, wet filter sounds of the original. Set the sensitivity with the GAIN control and the resonance with the PEAK control, and you’re good to go! It also features high and low range positions, lowpass and bandpass modes, and a sweep reverse. It has a wide sensitivity range that will drive active or passive instruments, and the filter range is such that it will sound great on guitar, bass, and whatever else you can throw at it.
