Hi - I hope you are all doing well. I am a new member, and would like to ask a question about the F-30, F-40, and F-50. I currently am playing an awesome westerly d-40, the loudest and clearest guitar i've ever owned. I had a chance to play a Hoboken F-30 the other day, and loved the size and sound of it. I am having arthritis type pains in my left hand and was wondering which of the Guild models are shorter in scale. I know this pariticular F-30 was. What about the F-40 and F-50. Are there any other shorter scale Guild flattops? Thx for the info. BTW - are these types of specs spelled out in Mr Mousts' book? I enjoy guitars in general and Guilds in particular that I should probably buy it...many thanks - FC
