Tried a set of GHS Signature Bronze but wasn't happy with them on my SJ-200 - there was a harsh, brittle sound that wasn't warming up as they wore in.
Decided to try a set of Rotosound Tru Bronze 80/20 Medium Light 12-54.
Straight out the pack I thought 'Oh no, these are too muddy sounding' and I put the guitar back on the stand.
Half an hour later I picked it up again and ... they sound way better!
There's something about this guitar and 80/20's and D'Addario NB's that just seems to work well together.
