Been playing a lot of acoustics lately...
The GS Mini is good but I have come across better!
Tried a PRS Angelus which was good (sounded great) but action was a bit high and it felt tough to play. Good sound, though..
Tried a L'arrivee D-02 which sounded AMAZING. Being all-wood the sound was so rich, I couldn't believe it! Going to try an OM-02 model next weekend... £800 and includes hard-case.
Tried Martin GPCPA4 and GPCPA5 guitars... Nice cutaway, looks great... plays VERY well (feels easier to play than the L'arrivee). The "4" sounded better than the "5" due to being all-wood and being made in USA ("5" is made in Mexico and uses HPL). The electronics included seem pretty good but not sure how often I'd use them. I'd go for a "5" but for £800 no hard-case is included which is a bummer. The only thing is, the sound of these guitars wasn't as good as the L'arrivee, but they did play better.
Guitarguitar's own brand, Finlayson, was also surprisingly good. All-wood and they cut out the middle man, so can sell them for a good price. Sounded REALLY good (like the L'arrivee), but perhaps not the same finish as a Martin.
