You may be overthinking it...
First question: how would you rate your technical facility on the instrument?
Second: What's your budget?
Third: What kind of amp/cab setup do you have?
Some expectation-setters:
- There's no such thing as a one-arrow quiver; an Ibanez SG Premium is about as close as you'll get without breaking the bank.
- There's no such thing as a good sounding B. There are ok ones, but to get one that doesn't sound like fart-like, the instrument scale length would be unplayable (think 5 1/2 feet). The best you can do is settle - the problem is physics, not quality. Also, you'll need an amp and cab than can actually reproduce those frequencies. Again, physics.
No specific budget. Whatever the bass ends up being that fulfills my requirements, I'll probably just save enough money to buy it. I try to follow the ideology of "quality over quantity" when it comes to tools. But the problem is that as I'm a beginner, it's hard to tell which tools to spend on. That comes with experience. So I may have to buy a few "duds" and learn from them what I did like and what I didn't like.
I'm using my instruments only in my home studio setup. So my bass goes to YYZ pedal (through various other pedals) and then directly to my mixer and/or audio interface. Then from there to my Genelec studio monitors + sub. So no cab nor miking needed. What I hear is what ends up in the song.
