i just bought a 2012 custom 24 and i'm noticing it has significantly more high end than the 2004 custom 24 i've had for 8 years now. both are mahogany bodies, quilted maple tops and rosewood fretboards, older one pattern regular neck, new one pattern thin...is it possible that the high end has dulled over time in the older one, or might the new ones just have more snap to em?
