The EQ is simply a Fender tone stack which has an inherently "scooped" sound - perfect for slap.  I've also replaced several other parts so that it has a slightly cleaner sound.

I've also made it true bypass by using a latching relay which is triggered by the original discrete flip-flop circuit.

For the audio example, I'm playing my '73 P.  You'll hear me kick the CP10 in after the 2nd riff.

I've put a fet buffer and a 3-band EQ in this pedal so I can dial up a really smooth slap sound.

I managed to squeeze the circuit onto this small L-shaped piece of project board.  I hard wired the original "Attack" control all the way back as this is where I had it permantantly set on gigs anyway.  This allowed me to remove it all together, and by relocating a few resisters on the secondary board, my tiny buffer/EQ circuit actually fits on top of the secondary board.  Using those tiny pots sure helps!.
