A little known fact is that the Earthquaker Devices Tentacle actually has its origins in another Earthquaker Devices pedal, the 3-in-1 Hoof Reaper fuzz. I love the Hoof Reaper fuzz, so much so that it made it onto a favorite pedal list of mine for Premier Guitar. The Hoof Reaper Fuzz has three switches, one for the Hoof circuit, one for the Reaper circuit and a bonus octave function to get those Hendrix-esque Octavia sounds.
The history may be a bit foggy, but it wasn't until Nathan (with some added reinforcement from other musicians) approached Jamie at Earthquaker about just making the octave function a separate pedal. Thus, the Earthquaker Devices Tentacle was born. In this video we go over the history of the Tentacle, and check out Nathan's prototype Tentacle, which happens to be the very first Earthquaker Devices Tentacle ever made.
