Is there such thing as a down octaver for bass?

[F2HF2H]

i want it to take the tone 1 octave lower for my bass..
Thanks

It can be done quite easily.  All that is really required is a small adjustment of ANY octave-down unit to be a bit more suitable for bass.

The more difficult question is whether your amplifier and speaker can reproduce such low notes.  Not all bass amplifiers can.

BTW:  My son's friend is named Shachar too.

Many thanks!
Do you have a name for any down octaver?
and where are you from? it's pretty rare to fimd us Shachars outside Israel

The MXR Blue Box (the Caja Azul project at Tonepad.com) and Joe Davisson's Shocktave are both worthy candidates.  So is the PAiA Rocktave.  Take note that the Blue Box and Rocktave both have 2-octave-down outputs.  If producing an octave down from a bass is tricky, you can imagine that producing two octaves down is an even bigger gamble.  The Blue Box can be easily modified to produce either 1 or 2 octaves down.  I've done it on mine, and it's no problem.  Just remember that octave-down boxes, unless they are digital, are always monophonic.  The good news is that this interferes with the playing of a bassists MUCH less than it interferes with the playing of a guitar player.

Ottawa, Canada (just took our sukkah down on Sunday) and "our" Shachar is also from Israel.

NB: 2 octaves down for bass gets into the inaudible region. The lowest note on a bass (standard 4-string bass anyways) is the low E, with a fundamental frequency of 41 Hz. One octave down is already lower than most amps will truly be able to reproduce... two octaves down will be inaudible no matter what system you listen on. You're human! Your hearing just doesn't go below 20 cps.

Of course, if you like to play solos and stuff on your bass, then the higher registers of the instrument might come through once transposed two octaves down. But the whole lowest octave of a bass (41-82 Hz) would be pushed into the inaudible by a two-octave-down pedal.

The Roland MC-202 has a very powerfull suboscillator, that can be adapted for bass or anything else.
Here's the schematic: http://www.kolumbus.fi/janne.husu/specs/202ana.gif
The octave down/suboscillator section is just below the CEM3340 VCO.

Because you have an square wave as suboscillator, you can hear frequencies below 20Hz as rapid clicks. Put these very low frequencies thru an almost self oscillating filter and your in outerspace bleepiness.

I bought a crate bass amp combo that has an octave control built into it when i first started playing.  It was pretty nice.

on the subject of frequencies.  Could you "feel" notes lower than 20hz or would it get lost in the mix and only be noticable with bass only playing?

Danelectro Chili dog $30 - DONE! :-)

50 bucks.  No idea what its like.  Chili dog may be better.  Read some reviews.

 The Behringer ultrabass circuit is an octave down effect. The Boss OC-2 and Dano Chilidog seem to be twins(I have both), and do the trick. I think Anderton's Rocktave divider would also be fine.

But.

I think it will not be as useful for you as you may imagine, unless you usually play high on the neck. These gizmos are not very good at tracking anything below a low A, so you must adjust your playing accordingly.
 
  As far as subsonics- yes you can feel them. The trick is finding and funding speakers capable of reproducing them.And, octave down ain't the best way to get there, because of the low note tracking issues. A synth will get you there without even breaking a sweat...
