Hi Barrie
This is a subject close to my heart, and I have gone for a really acoutsic, organic tone over the last couple of years.
[quote name='derrenleepoole' post='807588' date='Apr 15 2010, 08:34 PM']Godin perhaps, even though it is more semi acoustic? I would imagine even in a fully acoustic set, you're going to need amplification of some sort. With all the will in the world, and acoustic bass isn't very bassy without it![/quote]
+ 1 to this. I have a beautiful hand made fretted 5 string by Brook Guitars down in Devon. It's a serious high end bass and has the most stunning flamed myrtle back and side. It copes very well against two unamplified guitars when played with a pick, and has a pickup in it as well so I can use it "plugged" but still have the acoustic look.
If you want something that has a good acoustic vibe but is more like an electric to play then a Godin or any decent hollowbody would serve you well. I had a fretless Godin briefly and, while it was a bit of a one trick pony, it did that trick very well! However if you really want to splash the cash something like my Veillette Archtop fretless would do the job very well indeed.
And then, if you just want to look acoustic, a solid body made to look like an ABG is an option, just like the [url="http://basschat.co.uk/index.php?showtopic=82415&hl=samick"]Samick[/url] that has just sold in the For Sale section.
