Is it to learn acoustic guitar? I've tried to pick up bass long long ago, so I have a very crude understanding of how a guitar works.

Lately, I've been getting all these great idea's of songs in my head (and I have a basic mastery of reading/writing music) but I can't exactly put it into song without the proper tools. So I've decided to teach myself to play acoustic guitar,

so, those of you guitar junkies/veterans any tips/pointers? Also, if anyone has any suggestions as to the brand of acoustic to pick up that'd be more than welcome.

Please bear in mind that I don't work because I'm just like that and I don't have all that much money (part of the reason why I'm teaching myself after all) but I don't care about that stuff, I just want to make music.

Suggestions, points, advice, anything?
