Sustain issues on upper frets?

[charliebrown]

I have an Epiphone ES Les Paul where the sustain on the 20-22th frets seems to last shorter than the lower frets and my other guitars. Does anyone know if this is normal for Les Pauls or if it could potentially be a setup problem?

I have roller saddles installed if it makes any difference? Thanks!

Semi hollow will absorb energy and can shorten feeling of sustain

Lower the bass side of that neck pup ..may help ( probably not )

The strings vibrate more lower on the neck. The shorter the effective string length, the less it sustains.

Yup, I mean "this." Check your bridge height (string height at last fret). You might be a little high or a little low.
