I just bought another guitar (A) and put new strings on it (EJ46 FF carbon high tension). My old guitar (B) has the same strings. Side by side tests while rolling a chord, I can feel with my right hand fingers, that guitar A has less tension than guitar B.
I was very surprised I could feel the difference.
A has a slightly longer (660) scale length than B (656)
Both are solid cedar top
A top thickness is 2.7 mm, B is 3.2 mm
Action on both are very close to each other, A has slightly higher action than B.
A is ladder braced, B is fan braced
Body dimension of both are very close to each other, with B slightly bigger than A
Question is, what is the main contributor to the different feel? Differences in top thickness ? Scale length? Something else?
