    Heresy, I know.

    I'll leave you all hanging until I (and Janek) own a handful or I can get the circuit cloned...

    Are you talking about those old Pearl pedals from the late80s? I had one of those and it was great- had octave up and maybe 2 down, I can't quite recall. It died on me and I gave it to a friend to repair years ago and it disappeared into the ether.

    Yup, it had a fuzzy octave up too. I think the Pollyanna is a clone.

    Octave up, or down?

    If it's up, I'm interested in hearing more about it. If it's octave down, then I have no interest.

    Thanks!

    I'm always late to the party. Yeah, the Pearl, and glad to know it's cloned. I just got a nice one, so did Stu Brooks (we were fighting over one on eBay during Mark Guliana's recording session) and I think Janek, too at this point... I want to check out some clones now, and see how they differ from the original. Anyway, sounds huge and tracks great. It's a bit of a different vibe than the OC2. Maybe not as punchy or dynamically responsive, but as far as the timbre goes, it has more of a hollow square wave vibe... seems perhaps better suited to minimal tech and dubstep whereas the OC2 has more of a jungle/dnb vibe.

    I'm quite surprised that the OC-07 and OC-2 has a different sound on the -1 octave, as they - according to the service schematic - are identical in the -1 and -2 section (they use different germanium diodes, but both germ.). The OC-07 looks to have some more gain on tab though.
    The OC-07 does have the +1 octave to mix in, which might make things a bit more interesting.

    I think there are some vero-board layout at DIY-stompbox somewhere for those with interest.

    Ungh. I really do have to make a good synthy -1 octaver some day... Some day when time permits it.

    I think the MadBean Low Rider is based on the OC-07 circuit:

    http://www.madbeanpedals.com/projects/LowRider/docs/LowRider.pdf

    I borrowed one for a few weeks back in the 80s and loved it. Forgot its name until a few years ago when I saw one going dirt cheap - should have grabbed it, but I'd just bought two OC-2s!

    Looking at the schematic, it should be possible to leave off the -2 octave part of the circuit - not much use on bass. Then you could add a pot to change the frequency of the low pass filter part after the -1 octave to make a tone knob.

    Or I could just wait for my Subterranea to arrive!

    yep, the madbean lowrider is an exact clone of the original Pearl OC-7 circuit. I just finished building one last week. IMO, it's a very nice sounding pedal:
