After playing my mate's guitar, last summer I went out and bought a Rainsong OM10.

it is a carbon fibre jobby with no timber at all on it. It therefore stays in tune....

Soundwise, the strength of carbon fibre means no bracing, so non dead spot frequencies, allowing a rather clean sound. Acoustically, it is loud despite being a thin body cutaway and plugged in it has LR Baggs pickups. Nuff said.

Very very pleased with it, so the Martin, the Jim Harley and the Yamaha haven't had an outing since.

If I had any complaint, it is that the sound is a bit too clean, so every mistake is heard loud and clear!
