Ahh, yes... I remember that one now, you and Dan (frankfive) were eyeing it a while back. Beautiful bass there - Congratulations!
Good that they put it back to standard with the filter, as that's a great simple circuit. I have that same V-P-F setup in my bass, but with an added 3-position Q. (my bass had an extra hole left over from an earlier hack job) Plus, (as pointed out in the older thread) with those Bass and Treble pots, you always have the option of doing an East-Meets-West conversion later.
