Hi Chris
i acually haven't built it, but
U R correct, it is an octave-Up-type circuit.
I would do the mixing of the 2 activerectifiers a little differently.
Like, mix each separately AND series, total of 3 mixes.
Since all stages are inverting, an inverting stage after
each rectifier, also mixed in(now total of 5) .
Lots of mixes varies the fuzzffaazeing.... :-)
Oh, and ToneControl, FERSURE!

as 4 others---there's
OctUP!
HamonicExciter
HarmonicEnhancer(ETI?)
GreenRinger
FoxxToneMachine
FenderBlender
HarmonicEnhancer(EE-November1988)
EMM ShaperFuzz(uses envelope)
:-)

all i can thinkof right now.
maybe others have links/thoughts(?)
no links, u'll have 2 google.

I wouldn't call it clean. It just allows blending of the octave and the clean sound via level knob for each.

Thanks guys.. but i'm looking for a more clean octave.. no fuzz.

Tim, how about the back to back jfet octave on your site with the darlington.. is that cleaner (less fuzz) than the Octup Blender ?

Yes, it's cleaner.

One thing you might need to consider. I don't think there is such a thing as a truly clean octave up, unless you go with a good digital unit. They can all get pretty nasty pretty easily. Some of the "fuzz" designs can sound fairly clean when driven with low gain.
