Parts values for Green Bean

[smcv]

Why is C1 on the green bean 47n, and TS seems to use 20n ( .047 mic and .02 mic )? What is R1 for on Green Bean? It is not used on TS. Why is R7 47k on green bean? TS uses 51k. What is R21 for on green bean. Why is R3 470k on green bean and 510k on TS. Why is C3 on green bean 100pf and TS uses 51pf. Why is R13 on green bean 470k and TS is 510K. What is the voltage supposed to be at "VB" and "VC".
Thanks for the help

Simple...these are my tweaks to the circuit. 

20n is not a common value. 47n is much more common, although a 22n is probably just as fine there.
R1 is a pulldown which is not needed on the TS because it is buffered bypass and the Green Bean is not.
47k for R7 is just a more common value than 51k. The difference between using the two values is negligible.
R21 is to prevent switch popping when going between the to caps on the Fat switch.
Again, 470k is a more common value than 510k and the end result of the difference in the two values is negligible.
The 100pF is more of a personal choice. It means a little more top end gets filtered when the gain is closer to max. I find it works better that way with the active tone control which itself is capable of producing some fairly shrill tones when it is boosted. The added capacitance in C3 helps tame that.
The VC voltage should be about 9v and the Vb voltage should be about 4.5v.
