OK folks, here's the deal; I'm doing a little solo home-recording project (not a band!). I am planning on getting a hollow-body Epiphone electric guitar, and I have a cheap little guitar amp, and for now I will be using GarageBand to lay down tracks.

I'm trying to go for a garage rock/psychedelic sound similar to the following bands: Joy Division, Jesus and Mary Chain, Thee Oh Sees, the Fresh & Onlys, the Raveonettes, Spacemen 3, Crystal Stilts, Brian Jonestown Massacre, Beach Fossils, Wild Nothing.

I realize that ultimately I'll want several effects pedals. But here are my questions for now:
(1) What are the most basic ones I should get for starters?
(2) And, if you could narrow it down, is there any one particular pedal that I can start with as my first one?

Thanks!
