A friend of mine in NZ wants to get into playing bass.

Budget: $500 NZ.

Styles: He said slap, but I think he should get something versatile.

Budget includes both guitar and amp. He isn't going to be gigging any time soon, so all he needs is a practice amp, nothing fancy.

Thanks in advance.
I'm not sure about the money thing but, I would either go with the Fender starter pack or the Ibanez starter pack. Both of those are head and shoulders better than everything else.
Check out the FAQ there are some really nice options for beginning bass guitars and amps.

Any questions not answered there, come back and post again in this thread.
