Thanks for the discussion, gents. We are glad to work with redwood again. The last time was a couple years back, and I would actually welcome the chance to use it more. Like Mike said, you get the sparkle of spruce, and the warmth of cedar without its mushiness. And it pairs quite well with walnut.
Here's a link to a walnut/redwood guitar sound clip.
Keep in mind this clip is of our smallest model, a P-1 parlor:
