Apple Logic Pro /LogicExpress Discussion

I don't have access to any guitar players, and I need a strumming guitar
part in a song. It won't be soloed, but I do need to be able to choose my
own chords. The acoustic guitars in Logic are a bit rubbish as far as I
can see, and the ones that add chords have a very limited range of chords
(unless of course I am missing something, which I might well be).

Can anyone suggest an affordable and reasonably good and simple was for a
non guitarist to get something that sounds reasonably authentic?

The other thing I am failing with at the moment is a driving bassline. To
my untutored ears there are loads of very good bass sounds in Logic, but
no matter how much I practice, they just sound like me playing them on a
keyboard (and I am a pretty good keyboard player).  Any ideas, other than
find a bass player?


Thanks in advance
