I own two Elliot Easton guitars HD--2006 (#13 & 20) and I am impressed by the sound, sustain, clarity, volume, projection, vibration that comes out of that instrument each time I play...I also own a 91' HD-35, 2009 D18-V, 2009 HD28-V, and 2009 D42. None of them sound like the Elliott Eastons in terms of Balance, clarity, projection, sustain etc...A true cannon with that vintage bone sound but with unreal clarity and string separation..... Does anyone know the production numbers and which years there were made?
