Octave Multiplexer (EH 5900) (HF – B – BF) w/Original Packaging

Effect Information

Price listings here are for the original version of this effect from the late 1970s and perhaps into the very early 1980s. These have been reissued and were apparently manufactured between 2005 and 2008. The reissues included a “sub” switch and this version is apparently discontinued. A completely new version is also available from Musician’s Friend (and elsewhere).

This from a 1970s EH brochure:

“Now Synthesize a not one octave below the one you’re playing. The Octave Multiplexer literally allows you to convert any standard electric guitar into an electric bass – making possible lightning fast bass runs. An unbelievable extension for horns and trumpets. It explodes the tonal capabilities of these instruments into the range of the bass and baritone horns. Five filters allow the user to shape the harmonic content of the new note from fuzz bass to a pure deep organ bass. The Octave Multiplexer is fantastic on voice too; it makes any singer sound like Ike Turner. The Floor Unit contains all the basic controls of the pedal in a compact modular form.”
