I compared the two guitars with identical Martin M-2100 Phosphor Bronze strings. The 000-28EC has a warmer tone and more volume. Bending strings is easier, suggesting subtle differences in the frets. Finger vibrato is transmitted better. Hammer-ons work amazingly well for an acoustic.
Riffs flow better, as if the notes blend together.
Barre chords on the 000-28EC do not tire my hand as quickly. In summary, both Eric Clapton Signature Martins are beautiful guitars that play well and sound great. The 000-42EC is more ornate and obviously more collectable. Copyright 1997, all rights reserved. Japan Copyright 1997, all rights reserved.
