I can't speak to the Norwood shop, Steve Morrill did a change of routing on my W-strat. The work was done perfectly, at a good price.
He was recommended to me by the shop where bought my Martin, and as far as I know, he's the only local Martin certified luthier. He was working on an older Martin in need of some serious love when I dropped my warmoth body, I'm sure it went back home looking & playing much better.
His reputation is well earned.
