LOL I can't even find Redwood in California...I mean I can...but it's so expensive. If I ever find a big billet of it, I'll buy it up and sell it to guys who actually know how to build guitars
I played a few Redwood guitars and liked them. One of the more interesting ones was a carbon fiber bass guitar, that had a carbon fiber back and sides with a redwood top. It really sounded like an upright bass and had great projection.
I've heard a Steve Klein steel string with a redwood top and it was really amazing. But he's a steel string builder primarily.
It could be pychoacoustics but I think the Redwood has a little bit more treble on than Cedar and the midbass sounds just a touch sweeter...as in more balanced and full.
I just don't know but I feel passionate enough about redwood because it's part of my home state. I'd like to have a bit of the Pacific northwest in my musical instruments.
