Thanks for all the input guys, very thought provoking! Also apologies for the length in getting back on this thread, life took over for a little while.
It's a good question - what is 'wrong' with the current pickups. Well for a start, the single coil in the middle sounds rather thin, I never use it. It's certainly quieter although I guess this is to be expected? Perhaps this would be a candidate for raising, to get higher/thicker output?
I actually quite like the tone of the humbuckers, especially the neck one, but when recording, there's something about the attack of string plucking that i don't like. Sounds a bit 'plasticky'/'brittle'/'cheap'. I think that's what's making me look elsewhere...
But I totally get the view that maybe what I'd be better off thinking about is a new guitar...
Oh and the pickups on the Godin are:
Neck: GHN1
Middle: S1
Bridge GHB1
Seen one of those on Reverb for about £25, so they're not expensive, if that makes a difference...
