I've been seriously thinking about investing in a bass and despite looking at all the other 'beginners advice' threads, I stil need some help. I want to play a more slow, sludgey, very overdriven, very dirty, bottom heavy style of music (Sabbath, Electric Wizard, Kyuss, etc.) and was wondering if you could help me with a good start-up package. I'm looking for solid build quality and poweful sound over versatlilty. I'm budgeting at a maximum of £1k (about the same in dollars) for a bass, modest combo and pedals. I know that i'll eventually need to get a head and cabinet for gigging purposes but at least want a bass that'll last the distance and grow with me (so to speak) as money is very tight and I don't see myself being able to upgrade it for quite some time. Any pointers?
