I'm not sure that you will achieve much difference in sustain with the mod... I played around with the set-up on my RD - thru the body, on the three-point, Badass (I), but to me it made little difference... I agree with Uwe re the looks - imo they look better with a two-point bridge...
The timbers do play with the sound, much more than any bridge ever would... finding what plays well "in your hands" is best...
Much of it goes with "feel" rather than "fact..."
Also depends if you are a "Chrome-Boy" or are your leanings more towards "The-Dark-Side"
Curiosity here and a general question, considering the "Chromies" out there... did Veleno ever make a bass...? (can't get more "chrome" than that...!)
