Maximum Down-tuned Drone Metal

The EarthQuaker Devices Sunn O))) Life Pedal V3 is a heavy, crushing octave distortion tailor-made for droning, metallic textures. This ratty-sounding dirt pedal houses a tweaked version of its predecessor's circuit, along with a third footswitch with Flexi Switch Technology for extended real-time control of the octave effect. The distortion side of the Life Pedal V3 features Distortion, Filter, and Amplitude knobs for dialing in your grindage, while an Octave knob blends the analog octave-up effect with your signal. A footswitchable Magnitude function, which is EarthQuaker's clever name for an all-discrete MOSFET booster, dishes out all the punishment your amplifier can handle. You also get a 3-position Clip knob for tailoring the stompbox to your rig. If you dig the ear-splitting guitar tones on Sunn O)))'s Life Metal album, the Life Pedal V3 belongs on your short list — it delivers down-tuned, drone-metal riffage by the truckload.

A hotchpotch of droning distortion

Patterned after the guitar tones on Sunn O)))'s Life Metal album, the Life Pedal V3 combines a classic "White Face"-style distortion with an analog octave effect and an all-discrete MOSFET booster. The distortion section includes three knobs: Distortion for adjusting the amount of clipping, Filter for dialing in your tone, and Amplitude for controlling the output volume of the distortion. The Octave knob blends in the analog octave-up effect as you turn it clockwise. The Magnitude knob controls the output volume for the booster. You also get three footswitches: Magnitude for kicking in the booster function, Octave for deploying the octave-up effect, and Amplitude for engaging the distortion effect. To top it off, the Octave switch uses Flexi Switch Technology, allowing expressive real-time control over the octave-up effect.

Pro tip: Flip to your neck pickup and play single notes above the 12th fret for maximum octave-up merriment!

Three ways to dial in maximum grindage

The original rodent-style circuit employed a single pair of silicon diodes for its signature grit. The EarthQuaker Devices Sunn O))) Life Pedal V3's Symm setting allows you to dial in this double-silicon-diode configuration for the classic sound you know and love. But that's not all! You can also select OpAmp to remove all diodes from your signal path for full, grinding op-amp carnage or Asymm, which deploys two silicon diodes and one LED in an asymmetrical clipping configuration. The guitarists here at Sweetwater have found the Asymm setting to be quite tube-like: slightly compressed, smooth, and crunchy.

Rated 5/5

One of the best pedals I’ve ever owned.

This pedal does everything you expect it too… and more. There are so many sounds you can get out of this thing and so many knobs and filters/amounts of certain things to mess with. Plus this pedal works extremely well with other pedals, helping to make an even more monstrous bassy tone.

Impressive Versatility

Like most people I'm sure, I picked this up for the brutal drone metal tones which it does very well. However with the distortion turned down its a great dirty or clean boost (or both at once!) and the octave blend lets you bring it in just enough that it adds some color without making chords unintelligible. I was a little worried about finding space for it on my board but since it allowed me to ditch my clean boost and a fuzz pedal I was using as a dirty boost it really justifies the space. It could actually replace my normal rat (obviously) too but I'm having too much fun deafening myself with a wall of distortion by running the life pedal into the rat.
Rated 5/5

EQD Never disappoints

Very versatile and fun pedal! Capable of subtle fuzz tones, Rat tones, and complete devastation! Great pedal!
Rated 5/5

Praise The SUNN O)))

Fantastic pedal. Easily does the SUNN O))) thing. But definitely not a one-trick-pony. Surprisingly versatile.
Rated 5/5

If I could only have one pedal, this would be it (((O)))

I was looking to replace my Rat Distortion and I like the ProCo versions that are out now, just fine. Then this thing came out. I like the idea that this was a production version and not a geranium like the V2. Not that the V2 didn't sound good, I just prefer workhorse pedals over boutique stuff, if they are too valuable or rare and hard to replace, I tend to let them sit in a box. At any rate, this seemed to me like it may replace a few things I had on my board. It really does. I pulled four pedals off when I put this on and haven't looked back. It does sounds like Sunn O))) extremely well and I play a lot of drone, as I can make all the noise I want where I practice. This pedal is so much more than just a heavy gain monster. I play with a ridiculous amount of gain. Seriously, it's ridiculous, that's why I got this. But when I started exploring low gain sounds with the pedal, it was even more interesting than a double Rat style circuit with a boost and octave. They've got something really special here. I am more and more impressed with EarthQuaker devices all the time. If I could only have one pedal, this would be it without a doubt. Sweetwater was great as always, they had this in stock when no one else did and it showed up quick.
