Henry describes the life pedal v2

If we can take a quick tour of the front of the pedal, the top row is a Rat section. From left to right you've got amplitude, that's your volume. Filter, which just like on an original Rat pedal actually works kind of backwards from what you might think.

It goes counterclockwise, more treble, clockwise, less treble, and the distortion knob, has about 60 decibels of gain on tap. Below that in the center is a three position rotary selector from right to left, you've got symmetrical, which is standard stock to the original Rat design in the center is asymmetrical.

That's gonna give you a little bit more of a smooth tube-like valve amp distortion and then all the way to the left as OP AMP, which bypasses the diodes completely and is gonna be the most volume you have on tap. To the right of that is your octave blend, and to the left is the boost control. That's the volume of your boost called magnitude on the pedal.

One thing worth mentioning with that Octave is that it is an analog design, meaning it's monophonic. So you're basically going to get along best with playing single notes up the neck near the 12th fret on the neck pickup, just like your standard sort of Octavia type effects. It's probably easy to think that this pedal is just designed to do the drone metal thing and it definitely does that, but it actually does a lot more too. I've really enjoyed that. It is kind of just the best Rat you're maybe ever gonna hear along with a really cool octave sound and a boost.

It kind of does something really interesting that no other pedal I have does and is really inspirational in a full band context.
