Fulldrive 2: Mod Mosfet to (or schematic for) older version?

[ichilton]

I've read on a number of forums that the newer Fulldrive 2's, like the Mosfet version were changed to sound brighter.

I'm trying to find out what components were changed (and therefore if it's possible to mod a Deadringer to sound like the older darker ones).

Has anyone done any investigation on this?

Thanks,

Ian
