Depends on the wood. If you've got some kind of $$$$ wood top, show that baby off. Otherwise cover it up. Boring wood grain is boring (imo). joe
Good grain cannot be beat! I agree.....nice grain or a cool top needs to come through! I personally like grain and translucent tops more (although I do love some solid colors and own a couple of solid color basses)
I definitely prefer to see the wood grain, even if it's plain old alder. All the more so if it's figured maple or another exotic.
The only reason for paint is to hide a bad piece of wood! ...and yet two of the three basses I have owned were painted. Hmmm...
Grain... most definitely... Unless we're talking Sonic Blue... cause that's my favourite guitar colour.
Although my bass is midnight wine, I prefer natural wood. I saw a beautiful Fender Jazz bass at Guitarcenter, with the best woodgrain ever! But I wanted a P bass.
