My sitka top Brook Taw (really an OM type) has walnut back and sides

My other one is a Brook Lyn (really a 00) but has European spruce top with Brazilian R/W back and sides - and they sound very different. Also this one is a 12th fret join.

At the moment I much prefer the Lyn - but even though they are both Brook's there are too many variables to say why one is different to the other.

I have played identical OM Martins that have sounded VERY different to each other.

Its the joy of wood
