My favorite shapes are based on looks though I have played all of them and find them mega comfortable and a joy to play.
PRS DC - This is the shape I play 99.9% of the time. To me it's the sexiest and the most comfortable of all.
PRS 1980 - Emil's black sparkle 1980 makes me want to find one on the cheap and call PTC. Love symmetricalness.
PRS JA-15 - I dream of one with a wrap around bridge. If I don't score a production model first I will own one eventually.
Music Man EVH - I loved these guitars. They knocked these out of the park. One of my favorite headstock shapes too.
Most of my favorites are PRS which should come as no surprise.
What are your favorite shapes? Are they your favorites for look or feel or both?
