This post is another quick heads up. I have been using the 3 Leaf Proton Envelope Filter for a couple of months now on my go-to board. As an R&B/Funkateer, vibe sounds are a big part of what I do on guitar.
The Proton Envelope Filter has much in the way of tweakable features that give you a broad range of sounds. I was an original Mu Tron III owner back in the day. I will say that it is very hard to find the contemporary vibe pedal that gives the good usable tones with the variety of features available in the original. I think the Proton comes as close as it gets! I will let the video do the talking. It is very well done and covers all of the bases. I will tell you that this pedal sounds great in my live power trio setting. The size and quality build with top inputs (including the 9-18v input) make it a serious addition to your pedalboard!
