I am very happy with my Eastman 504, it is great for folk, blues, celtic and even rock. However, my interest in bluegrass is developing, and I do think an F style or an 'f' hole A model would be better for that. Apart from the additional punch, the longer neck would be handy for getting to the higher frets.
I was set on an Eastman 505/515 or 605/615. Recently, though, I've wondered about saving fror a bit longer and trying a Gibson.
Realistically my budget may make that impossible. I reckon £700 GBP will be the absolute ceiling, and that would be on a good day with the wind behind me. £600 - £650 is a safer range (without getting into court order and baliff territory).
So, in the real world, what are the chances of getting a worthwhile Gibson 'f' hole mando in either A or F style for that kind of money?
If there's any chance at all, what do I look for? And what do I avoid?
Thanks for any advice.
