But my query is not about the tension of the strings.. but the strength of the join will improve the resonance of the tone. There are a lot of factors that play, the joint is just one of them.. this is why I wanted to know if anyone had tried it on the ASAT
My response was primarily to your question about the strength of the neck joint:
My wonder is the joint.. being that it is only three screws.. I am curious if it will be strong enough!
The answer to that is yes, the joint is strong enough. The quality of the feel - that's a whole nother can of worms I rarely open. I can't do 5s and rarely leave a bass in BEAD long enough to have an opinion or input. But I wouldn't hesitate to use an ASAT or any G&L for it.
