Replaced the Gibson three point bridge with a Hipshot. Quite amazed at the difference it's made. Should mention that I changed the strings at the same time (from Pyramid flats to La Bella) which might partially account for the difference but.. sound is very different; more driven tone, sustain much improved. The Hipshot is not as big as the Babicz replacement and seems more in keeping with the design of the bass. Very impressed with it, a worthwhile upgrade.
