Richard, If I ever get to a shop in the city, I'll try one of those Seagulls to find out what they are like.

I'm not at all up on what is around but let me suggest:

£700 to spend on a new (ie not used) guitar. Mostly folk ranging from to strumming "wild rover" to simple single note melody. Mostly flat picking but with bits of simple (eg. freight train) finger picking. Mostly unplugged but capable of working well plugged in. Preferring warmth and deepness to "brassiness" but perhaps as you suggest needing a bit of cut.

Just a curiosity question. What would you have suggested I looked at as a sort of all rounder for that?
