probably get railed for saying this, but IME the type of wood used in the body contributes less to the tone than the pups. In my opinion, the cheapest body paired with the most quality pup is the best bet to get good tone ON A BUDGET. I will admit, i'm not crazy about the neck on my affinity. But, that is only because I prefer THE LOOK of the adjustment at the heel instead of the headstock. Everything else about that bass is fine. The original pups and pots were junk. It only took me a week of evenings and $180 to totally refurbish a used affinity P. total. I don't think there is a better platform for modification than an affinity. They are extremely inexpensive when you buy used. Check craigslist, there are 4 or 5 on there now in the Baltimore/Philadelphia area right around $100 and I bet you could get them fro $75. Then get all your parts in the TB classifieds. I'm definitely doing an affinity j next. It was a really fun project. Of course, this is just my 2 cents.
