Speaking of switching - anyone looked at the Danelectro switching?

I recall someone talking about the Danelectro switching and how it was implemented well. I have a Fab distortion lying around. I wonder if I can take good enough macro shots of the board? The SMD circuits are hard to see.

I seem to recall it's 4066 based.  For their Fab series, the in/out/power/switching is all on a separate PCB that's common to all the models.  There are probably a fair number of these boards that are sitting unused after someone re-housed their pedal and true bypassed it.

i found the Fab-tone schem..
Actually is pretty interesting:

it´s a 4013 flip flop (in parallel, or with debouncer?) driving fet switches directly, with no buffers.

Wow. It will take a long while for me. Is Q2, Q3 and Q6 controlled by the 4013 circuit (on the bottom)?

Huh, interesting switching scheme.

looks like they are indeed..

That looks to be the original, big, metal, maroon fab tone from the 1997 on the schematic.  The mini dano's use analog switches, and I believe the plastic Fab's as well:
