Well....
A couple of things pop up every time the ABG question comes around.
1) Cost. We all have our budgets, right?
2) Feel. This seems to stand out a little more with these than a regular electric bass, just because of body shape and neck scale.
3) Volume. Yes, my friend, the bass frequencies require a large resonating chamber to accommodate them. This is why traditional bass instruments are bigger than their higher range sisters.
4) Tone. Surprised that this is the last on my list? That's because I think it's the last one most people's list. Great tone is expensive for an ABG and most people are more concerned with having an ABG for gig-appropriateness than for having one for the sound.
Here's what I recommend: Buy the biggest bodied ABG you can afford and get your arms around. Most of the ones on the market now are rather slim, so they don't carry the weight of the low frequencies unless they are plugged in. But the big ones sound better. You're looking for "deep". The extra size gives you the bass frequencies, and last time you checked, you're a bass player. Don't worry the highs will be there, its an ABG.
I play a Guild B-30. Of course they don't make these anymore, but if you're patient, you can find one on ebay. Should be $1k or less. The old Australian Taylors are amazing but you probably can't find them. American Taylor is definitely not the same thing.
Good luck on your hunt, and enjoy the acoustic gig format. It's a lot of fun and if you really get into it, you might find that it improves your technique and your ear.
And you can play it on the beach....
