jacco said:I don't think you can pull these factors apart in this case. I think that first the importance of glue regarding tone must be determined before we can go any further.
I think we can safely ignore glue type entirely, because what we should do is compare some of the same guitars with crappy looking joints to those with good joints and see if there's a difference.
No MIJs use hide glue AFAIK so I don't think it's of any relevance.
