Fender has a line of amps out called Rumble i think, they basically cost a dollar per watt. the 500 is nice. the 80(or whatever the little practice one is) is nice too. As far as cheap they are good.
Oh and "I know when you start, your supposed to get something like a P bass with passive single coils and four strings, and I was going to (honest!),"
NO, my dad bought me and my brothers professional gear right off the jump, it makes a world of difference.
I have 2 pieces of advice,
1 space your fingers one per fret, (f,f#,g,e flat) and go up all 4 strings like that, go up a fret and do it again, with a metronome.
Play until your fingers bleed, then tape them up, and keep playing.
Great bass for the money, the wood would cost almost that much, replace tuners first, then the preamp. I would get used stuff from our classifieds.
