My Axe for the last 3 years has been a Fender Acustic (with pickup and internal eq)Cant tell you the Model cos its at home and I am not!
I regularly play in acustic sessions against 2 or more fiddles, a couple of guitars, mandolin, smallpipes and various boxes (noisy buggers!) The fender seems to cope very well and pushes a big sound out front. The difficulty is in hearing yourself when behind the instrument! Tried various makes before I settled on the Fender, all side by side in the same store. The Fender had the best sound/volume/playability/cost compromise and has been robust in regular use. It cost me about £350 which usualy means about the same in Dollars when buying equivalent in the States so I am told. The secret of the Fender, I find, is that it can be played very hard, lots of energy from left hand fingers, without sounding twangy and just plain bad which few other Basses will stand. You will need to develop fingers like a Blacksmith to get the most out of it tho!! Les`s Ovation is nice to play but has half the volume of my Fender. Strings can make a big difference. Had a new set on about 6 months ago and when I broke one and put one of the original strings back on as a replacement the difference was striking. Well worth experimenting with strings if you can afford it. Still doing this myself but no conclusions as yet. About 10 years ago I also had an Ecko accustic Bass which I also had great service from and which also threw out a big sound. Worth trying if you can find one. Good luck, let us know what you decide.
