Description:

From the online manual:
The Electro-Harmonix OCTAVE MULTIPLEXER is the result of many years of engineering research. To get the best results from it please put aside an hour, or two, for practice in a quiet room…just you, your guitar and amp, and the OCTAVE
MULTIPLEXER.
Plug your guitar into the INST. jack and connect the AMP jack to the usual input of
your amplifier. Note: the battery is engaged when a cord is connected to the INST.
jack. Unplug to switch off and conserve the battery when unit is not in use.
Turn the blend control fully clockwise and hit the bypass footswitch to compare the
natural sound with the sub-octave sound.
There are four controls which affect the sub-octave sound. The most important is the
BLEND control which combines the natural signal with the sub-octave. Turn the
control clockwise to blend-in more of the sub-octave.
Bass Filter emphasizes the lowest fundamental note, and should be used for bottom
string playing. The knob should be set counter-clockwise to get the deepest sound
and the bass switch turned on. For higher strings the high filter is used and the bass
slide switch is turned off.
The range switch should normally be down when the MULTIPLEXER is used with a
guitar to produce a deep bass sound. When it is up, the unit accepts much higher
notes and inputs from other instruments. Some guitars may work better with the
switch up.
Playing technique, The OCTAVE MULTIPLEXER is really a one note device. It
will not operate on chords unless the lowest string is hit much harder than the others.
For this reason, you should keep the silent strings dampened, particularly when
playing rising runs.
Clean Triggering, some guitars have body resonance that can over emphasize certain
frequencies. When these coincide with the first overtone of a note played (an octave
above the fundamental), the OCTAVE MULTIPLEXER can be fooled into
triggering on the overtone. The result is a yodeling effect. On most guitars, the
rhythm pick-up (nearest to the fingerboard) gives the strongest fundamental. The
tone filter controls should be set to mellow. It also helps if the strings are played well
away from the bridge.
One other cause of dirty triggering is easily remedied – that is the replacement of
worn or dirty strings. Worn strings develop small kinks where they contact the frets.
Those cause the overtones to go sharp, and results in the sub-octave sound glitching
in the middle of a sustained note.
The small jack on the OCTAVE MULTIPLEXER is for a 9 volt battery eliminator
capable of delivering 100mA of current. The unit’s battery may be left in or taken
out when the eliminator is in use.

This is as of yesterday my no1 pedal.
Ive had it for quite some time.. but after rolling of 20% of the max volume on my bass I found this pedal to trigger all the way down to my loose e-string.. 
This was discovered by accident when I was testing the Little Big Muff fuzz by ehx.
By far the best triggering and sounding octaver ive tried..
This is as many other octaves a "One note samba".. It does not trigger well with several notes @ once / chords..

this is the larger older version of this pedal, it sounds identical to the smaller newer one.
it tracks well and with the blend knobs gives you enough control over your sound. the octave is slightly distorted as all ehx pedals are. no way to get away from that. also it is not clear and strong as other pedals are. you can hear the lower sub, but a lot of coloration as well.
