looking for an octave up/down pedal and ran across this one. loved it, but way to pricey. does an analog clone exist?
BYOC Divided Octave maybe?
Or there might be an eh deluxe octave multiplexer somewhere..
There are projects for the Pearl Octaver.
Here's a clip of the original.

EH deluxe has excellent fundamental extractor which is vital for decent octave divider, but needs 2 x CA3094 in its Adaptive Filter. Should be a way of adapting this for LM13600 - I think someone had a go at this a while ago :icon_biggrin:
From Mike irwin in 2004:
Subbing LM13600 for CA3094 - this can require some care - since the Iabc pin on CA3094/CA3080 sits at one Vbe above V(-), whereas the LM13600/13700 Iabc pin sits at two Vbe above V(-). Can make a difference depending on how current is being supplied to the pin.
I thought this was just a tweaked OC-2 clone if I remember correctly.
BUMP
Octron-2 and Octron-3 are intersting variations of the Boss OC-2

It works just fine with a LM13700 ;)

I'm all for DIY, but I will say that the Octron 3 is an awesome pedal and completely worth the asking price. It's the sort of thing that inspires creativity.
I made a stripboard layout a while ago. I am yet to test it but if you want you can try it.
