I have all my basses set to the exact same height, measured at 7th fret ( for neck relief ) and 21st fret ( which is usually where the neck meets the body )...
E -- 7th fret....2/32 (1/16) just a 'micron' over 1/16 to be exact.
E -- 21st fret...4/32 (1/8)
A -- 7th fret....2/32 (1/16)
A -- 21st fret...3/32
D -- 7th fret....2/32 (1/16)
D -- 21st fret...3/32
G -- 7th fret....1/32
G -- 21st fret...2/32 (1/16)
((NOTE: these are pretty close, the way I actually measure is from the fret to the top of each string. I can get a more accurate reading that way...))
All 3 Yamaha Attitudes are adjusted this way...as well as my Thunderbird ( gotta have at least one classic bass )
My Rickenbacker is set a bit lower as well as my fretless Yamaha.
The Hamer 12 string is a nightmare ( I ain't even gonna go there

)
My Yamaha BEX-BS Semi-hollowbody.. is adjusted just a touch higher than the normal measurements... so I will play it cleaner. Found this works better on hollowbody basses.
I just picked up a Ibanez SRX500 ( some kid came in and traded it for very cheap, and I felt i needed a 24 fret bass again ). I have the action adjusted pretty damn low... I haven't played it live yet, so it may change...
These measurements have served me well for a long time... and they are the foundation to all the bass set-ups I do in the shop.. it is definately a LIVE BASS setup.
HAVE FUN,
