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

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.
