I was thinking that an ash or alder body in the manner of a Warmoth might retain the essence and the original intent of the T-40, while making of it a more user-friendly instrument. So often, I see T-40s on the chopping block for the simple reason that they weigh too much.
I think that most of what a T-40 "is" happens to be an assemblage of parts, rather than any one component; the body for instance.
On the other hand, I wouldn't know. It may be that the T-40's body, burdensome as it is often purported to be, is the true carrier of the instrument's spirit. But any attempt to lighten the load would be a step in the right direction. Has anyone done this? Your results?
