Hi I'm new to this group. Here's my question I have a blonde Guild X170 built in 1988. It has the 5 piece neck like the x500 x700 and Artist Award. I saw one more blonde with the 5 piece neck on Reverb.com. All the other X170 s I've seen have a 3 piece neck. If I could I'd like to find a 5 piece in a Natural X170. Any idea why they used a 5piece neck for such a short time?Thanks.Bobby.
