Octave Multiplexer Analog Sub-Octave Generator

Get down! Generates deep, phat bass tones one octave below the notes you play. Two separate smoothing filters enable you to tailor your sub-octave signal to the exact bass sound you desire, separating the Octave Multiplexer from other octave devices. Run your vocals through it and sound just like Ike Turner. This is a monophonic device and works only on single notes.

Skinny Music TV reports on five EHX pedals.

These pedals were conceived of and designed by EHX from globally sourced components. Every EHX pedal goes through a stringent testing process by musicians and technicians in NYC before packing.

Effectologist extraordinaire, Bill Ruppert, defies the impossible to re-create the theme from the movie Blade Runner. Using “only” his Electro-Harmonix pedals and unbridled imagination, the maestro delivers an auditory tour-de-force.

Please note: Bill will be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

Want to put some thunder down under and some junk in the trunk? Check out the “Fuzz Bass” effect. It’s been used by The Beatles (“Think For Yourself”), Sly & The Family Stone (“I Want to Take You Higher”), U2 (“Get On Your Boots”) and countless others.

Running your guitar into an Octave Multiplexer and any one of the Big Muff pedals generates a thick, distorted, sub octave that will shake the walls. The Octave Multiplexer uses an analog flip-flop circuit to produces a unique, fat, grainy sub octave tone.

Settings and sample video are below:

Sonic master Bill Ruppert reproduces the legendary Pink Floyd synth textures from “Welcome To The Machine .” Using only his guitar and the perfect blend of EH pedals, Bill re-creates the amazing sound-scapes that made this recording special. Each EH pedal provides its own magic to reveal the complexity and textures of the EMS VC3 synthesizer with stunning accuracy.

Please note: Bill will be in the EHX Forums to discuss his sounds, settings, and process. We hope you join us there.

Thanks to Andrea Rocca, guitar player with psychedelic blues band Gobuzli, for letting us know about their new and densely-animated video for "Strange Objects" from the forthcoming album "Abstract Origami Black Belts."

My personal favorite 'strange object' is the half-Stereo Electric Mistress, half-Octave Multiplexer, guitar-playing robot pictured below. Also stay on the lookout for the TV-headed vintage EHX Switchblade (for comparison, here's the current Switchblade).

Finally, make sure to catch the massive Stereo Electric Mistress sweep that kicks in at 1:23, and then lasts for a solid 30 seconds.

Thanks to Nir Yaniv and King Cano for sharing this 2880 live looping video. Nir adds: "The 'Beat This!' video was recorded live. You can even see that behind us there's a computer screen with Logic opened and recording. And let me take this opportunity to thank you and the others in EHX - that looper changed my loopin' life."
For more info, see the King and Nir site as well as Nir's solo site VocalMan (in addition to the 2880, Nir also uses an Octave Multiplexer).
