Been trying to figure this out.....I have a 2010 vintage mahogany Starla core and a 2011 ice blue core. They sound very different in terms of treble. The 2010 is very bright and the 2011 isn't. The wiring in both is correct and the same.....but the 2011 sounds noticeably better than the 2010, as far as highs. I've spent alot of time adjusting the pickups and pole pieces up and down to compensate but it just doesn't matter. Is it normal for them to vary this much ? Also the 2010 is twice as heavy as the 2011, have no idea why, it's like les paul heavy. Somebody help a Starla newbie !!
