Bass overdrive

[icecycle66]

Legend has it, that this is the scheme for the Boss ODB-3.

As hard as I've tried, I've never been able to kick it off my pedal board.
If anyone gets bored and feels like Diptracing/Eagleing a schem, here's this one.

A prize goes to the winner. Bonus for a printable layout.

Yikes - 5 pots, one of them dual gang, and an unnecessarily large circuit! I'm impressed Boss fit this all into their little package...

Boss uses 9mm pots, one of which here is dual concentric.

A lot of the transistors are current controls, protection, and/or working a bit like diodes and there aren't a bunch of parts associated with them. Plus it's essentially parallel clean/dirt circuits, AND it has an active 2-band eq. I don't think the circuit is unncessesarily large at all, though there are certainly places where it would be simplified by someone who's not completely anal about best practices like a Boss engineer. They overengineer a bunch of their stuff.

Granted, it's still probably not a 1590B build without some gymnastics, but 125B or a Bear Box certainly seems possible with through-hole parts. I mean, we fit Klones in 1590As these days ... the world's our small enclosure.

Sold mine, would love to build a true bypass version

Sold mine, would will love to build design a layout for a true bypass version

Fixed.

thanks, when may I build one?

Looks like Jimilee just got voluntold for a project.

When you design the layout of course!
