I recently built a Bassballs and I liked threading into synth-y territory. So, in the same spirit, I'm building a Boss OC-2 Clone, with the Pearl OC-7 upper octave part. It works well and I like the octave up better than the Pushme Pullyou that is added to a simplified OC-2 schematic.
I'm satisfied with what's on my breadboard, but, of course I'm wondering if I can get bettter/more effective.
So, questions:
-Anything new on the 'better tracking' front? Aside from the classic strategy of rolling down the tone and using the neck pickup.
-Any mods to make the upper octave stronger? Aside from etc...
-Would I gain anything at all from matching diodes in the rectifier stages?
Just makin' sure I didn't miss any mods. Any help appreciated!

there are ways to make the octave sound better through filtering and clipping.
that clipping works more as a wave shaping device that a normal distortion function, the gain before clipping needs not be high, in my experience is a gain of about 10 more than enough before that clipping, but i used different opamp rectification than the pearl pedal does, so your mileage may vary.
matching diodes probably won't make a difference because they're in a feedback loop of an opamp.
i have no adivce on the tracking tho
hope this helps,

Alright, thank Iain. I'll try adding more filtering and see where that gets me.
Madbean Lowrider, latest version (archived on Madbean website), listed as improved over OC-7
i mainly wanted to emphasize clipping, since that wave-shape function kind of tames the spiky nature of rectified waves.
cheers
So I went and raised R7 (Boss schem). It helped with the octave, a bit more pronounced. I'm staistfied. Thanks!
I just finished a layout for The Engineer'S Thumb compressor. I'll start on this one later.
