I know nothing about bass except my observations. It seems that many bands' bass players aren't using a lot of hand work; only one or two strings are being plucked at a time. Does bass look easier than it really is, or is it easy in actuality? Is bass easy for guitar players? Is bass generally more or less fun to play compared to guitar?

Ooh, that's a lot of questions.
Answered in the order you asked.

Generally that's true. Most bass players in commercial rock music follow the guitars or do nothing particularily fancy.

Somethings are easier than others, like guitar.

If you use a pick, it took me a while to get used to the scale length and finger style picking.

I think bass can be more fun when I do slap stuff. Guitar's cranked and wailing can be quite fun too.
The UG Awards exist only to instill me with existential doubt.

For me, the 60's ended that day in 1978...

Willies. Fuck the lick and fuck you too.
