First of all, I don't buy instruments now. If i want one, I build it.
But playing the game as described......
Choosing from
Musicians Friend's website, which is pretty much where I'd shop...I'd get a Fender American Deluxe Precision. Sunburst w/ a rosewood 'board. Good quality instrument, in a P/J configuration. Would do anything and everything I need it to do.
For an amp, the Fender TB-600C Bass combo. 400 watts by itself, with 2 10" speakers.
I'd pair this with a Fender 15" cabinet, which would bring the wattage output to 600 on the amp.
The reasons for these choices are simple. I play in church, and it's a small one. Most of the time, I would use the amp by itself. there's absolutely no need of the cabinet for 95% of what i do. For larger venues, to push a little more air, or for outdoor events, to give me a little more bottom, the 15" cab would be nice to have.
Given that I actually own no bass amp at present, but play out of the church's 20+ year old Roland Cube 60, I'd be in hog heaven with just the amp mentioned.
As for the bass, i already have a wonderful P bass built by my own hands, so I really only need the amp.
But if I had to spend the $4k to receive it, those would be my choices and my reasons.
