    It took a few runs to dial in the tones I was looking for, but this envelope filter is a monster. It's tracking well with both my Strat and Les Paul, and has fit in well towards the front of my pedal board. I was able to play the Keeley Neutrino prior to purchasing the Proton and thought it sounded good, but I think I made right choice for what I was looking for.

    Love it. I had a "real" Mu-Tron III back in the 70's (it was stolen), and this 3 Leaf seems to get the closest I've heard to the sound I remember. This one seems more versatile, though. And Cheaper. And smaller. And it's powered by easier means.

  • Mmmmmm Good

    They done well with this pedal. Closest I've heard to a true Mu-Tron which my bass player owns.

  • Funky-Synthy Bass Extension!

    Lots of reviews describing the tone. I'm here to say it plays great with active basses. Responds really well with effects before and after it. The good stuff!

    This thing nails the Mu Tron sound, which is exactly what I wanted. I'd replace it if it got lost.
