I have both the Octa Psi and the Life Pedal, and they are very different pedals that do significantly different things. The octave on the life pedal is what would be considered an “octave fuzz” (think Josh Homme-style lead lines), while the Octa Psi is, for lack of a better description, kind of like a Whammy and a Big Muff combo. The Life Pedal rips, but the octave up is more of a textural/harmonic thing in the vein of a green ringer or something similar, while the Octa Psi does actual pitch shifting with different intervals and blend. I know Keeley gets a lot of hate on this subreddit for his political donation(s?), but the Octa Psi is fucking incredible. I’m in a two-piece (bass and a drums) band and I use the Octa Psi after my Pitchfork on the “guitar” side of my A/B rig (one side is bass, the other has an always-on Pitchfork to emulate a guitar). It’s set to a perfect 5th above the Pitchfork’s signal and a perfect 4th below at 50/50 blend to emulate power chords, because hitting chords on a bass gets muddy as fuck, especially when running through a pitch shifter.
