I saw a matching set of custom shop Les Pauls years ago- one was a flame top standard, the other was a quilt top custom- both in tobacco burst. The flame top looked soo much nicer
With everything being veneered and photoflamed these days, soon I don't think flame and quilt tops will be all that collectable
I really doubt anything made today will be very collectable because they're made in such large numbers
I figure REAL flame and quilt will be just as collectable, if not moreso as quality pieces of wood become harder to find.
IMO a quilt top NEVER belongs on a les paul.
