Electro Harmonix – Octave Multiplexer Analog Sub-Octave Generator audio review,
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.
Test scenario:
Shure Sm57 and Sm58 placed in front of Fender Champion 600 amp as seen below,
Amp as usual placed on cushioned stool 9-12 inches off floor and in the centre of a large room.
Pre-Amps used are Behringer 1622FX Xenyx built pre-amps.
Guitar is a Mexican Fender Telecaster fitted with Seymour Duncan bridge pickup.
Guitar leads used are Planet Waves.
To accentuate effect a Electro Harmonix Double Muff has been used set on Single muff and set as pictured,
Volume on amp is as below,
