A SIMPLE OCTAVER DOWN
Hi,
this is my little contribution.
A simple octaver (oune octave down) based on M51134 IC, a chip found in old DOD MEATBOX and Behringer bass amps.
The octave works well with bass guitar. There is a sort of divider noise but with very low volume . This noise disappear with a buffer in front.
Enjoy.

Mmm.. really interested in how this tracks and what it sounds like got any links to clips?
Never mind, found the meatbox vids and it sounds pretty bad

here is a little sample. The first lick is bass only. The octave level pot is about 1/3.
Two corrections :
- R9 set the input gain . Try with values from 82K or change it with a 200k pot (higher values causes distortion)
- C6 set the low frequency cutoff. Try 1uf. Higher values causes rumble noise

it sounds great !
the plan is very clear, much more minimalist than the OC 2
i'm really interested in building one...
quite busy those days, but I will plan this for september.
maybe it could be the occasion of a transcription on CAD
did you mount it on stripboards ?

Errors like that tend to make my day. "Franger" from the Ibanez UE400 PCB silkscreen, "Batter snap" from Shin-Ei, etc

There was an effects related page that showed a schematic excerpt with a frip-frop years ago. No clue which one.
the jewel is pretty brilliant!

Resurrecting an old thread. I am transferring the hand drawn schematic to Eagle, but I can't locate R18 and R19 on the schematic. ( both 47k )
Also on the BOM the two 100R's in the power section are omitted.
