*Any* Bass Octave Pedal

[negativefx]

Looking for a good vero of a clean/minimal-fuzz bass octaver.  1 or 2 steps down would be excellent.  Up and down octaves is a bonus.  I've been unable to find much around the net in terms of schems so hoping someone else has a recommendation for specific pedal.  I'm currently using an EHX XO Octave Multiplexer and it just can't hang with the low E on my bass but the D/G strings seem to do OK.

Found this MXR Bass Octave Deluxe schematic:
