Here is my little story...
A few years ago I was on holiday near Exeter
We popped in to Exeter City Centre for a spot of sight seeing and shopping
Little did I know that MANSONS Guitars were tucked away within a little shopping arcade
I had been thinking of getting a good acoustic for a while so I played through every single acoustic in the shop including Martin, Gibson, Taylor etc.
The guitar that stood out for me was a Martin OMC 16 RE AURA
I was looking for "that Martin sound" and a guitar suited for gigging
The Aura system is absolutely superb and the sound of the guitar is amazing
Needles to say I bagged it - it was around £1,500 but it had a fantastic rosewood body, solid spruce top and ebony fingerboard and bridge
It is absolutely gorgeous and also records extremely well
I tried MUCH more expensive acoustics that I didn't were a patch on the sound of this one - and there is the "nub"
I think acoustics are much more subjective in tone and feel than electrics so I would endorse what James said about playing as many as you can and I am sure one will call out to you - and hopefully it won't be the most expensive one!!!
