I bought a set of 1/2" post Ultralights here on TB for a good price and installed them in my Tribby. I removed the neck, pulled the old tuners out and got the sleeves out by tapping them with a hammer and screwdriver. The G&L holes are slightly larger than the Hipshot sleeves so there's a bit of play but it's not a problem once they're tightened down. I like how the Hipshot tuning keys don't stick out as much, looks neater. And they really are lighter!
Weight of bass with stock tuners: 11 lbs 2 oz
Weight with Hipshot Ultralights: 10 lbs 4 oz
Still a beast, but much better balance now, no more neck dive when strapped on.
