I call it the Bitmap BB, it is essentially a big muff on a somewhat larger board and a bit more space between components. my initial aim was to build a sort of testing ground for BMP based designs, and mix and match values to see how much of an effect it would have on the overall tone. it does double up as an enclosure friendly board; you can directly mount alpha pots onto the solder side if you're into that sort of thing like me.
there are two mods: diode lift makes for a big addition of a heavily boosted clean signal (although, my signal is so bass heavy on full guitar volume i was worried for my speaker) and the tone stack mod, which basicaly sets the EQ flat or boosts mids by connecting a 6n8 or 22 cap in parallel with the stock 3n3. use an on-off-on switch for this.
there is no filtering and no polarized components. you can add this separately. this was intentional since i wanted to test some germanium transistors in the same circuit.
also, there is a jumper denoted by the red line in the third PDF.
if you want to try different diodes, the spacing grid allows you to use cut-up IC sockets
pop 'em in and out. hope you enjoy this. if you do build this, tell me how it worked for you. thanks for reading!
THANKS: gauss markov's excellent DIY site - his schematic was the starting point. also, i'm going to go right ahead and thank marc/skreddy for being open about his work here and even sharing a schematic or two.
Typo or personal taste?
that pretty much was my objective, making the PCB easy enough to substitute parts, perhaps one could add SIL sockets and mess around with biasing resistors as well? 
this PCB is designed differently with respect to potentiometer positions. they're now arranged in a triangle. the board was growing too large horizontally, so i decided to place the volume pot below the sustain and tone pots.
