Recently, there has been a move to produce lighter basses, but after experiencing light basses - most basses are heavy to me. Everyone has their personally tolerable range - mine is right around 8lbs. Some players don't mind - but many are coming around to enjoy a bass that's easy on the shoulder. Add to that a bass that is designed well (aka - hands-off balance) and comfortably ergonomic - and you have a bass you could play all night!
The myth that a bass has to be heavy to sound good is just that, a myth. It's like a drummer who sez' you have to hit hard and play loud to sound good. (
ah... no, that would be over-compensation to make up for a lack of finesse) There have been a number of really cool vintage basses over time that are over 11lbs, some 13lbs! I've got many comfortably light, great playing/sounding basses, both vintage and ones I've made to want to buy a heavy bass regardless of how it looks or sounds. But I always enjoy hearing/watching players who play them - they do sound good... but usually it's the player who sounds good.
Short answer - my solid mahogany Epi T-bird (who knows when/where made)
was heavy according to what I think is heavy as a player of it.

Even with all my lightening - it's still closer to 9lbs than 8lbs.
