It'd easy to say "they should do this, or they should that"; but without been privy to their actual sales figures for particular models, and perhaps even more important their long, long experience with "radical" musicians with their radical tats, piercings, hair, drugs and all - who want nothing more than a picture-perfect '59 Tele just like the one Grandma used to play - it's mysterious to try to out-guess what would, and wouldn't, work. "Work" in the financial sense of action=money. I would hazard a guess, a wild-assed one at that, that the suggestion box here on this forum probably has more peachy-keen ideas collectively than Warmoth receives over the transom, mail, phone, e-mail all put together. And the suggestions here get a certain permanence, even a lee-tle momentum through repetition. But - there has to be a certain number of sales to reach a "break-even" point. And even the tiniest little bit of innovation off the Fender standard invites a whole slew of "Waah! It doesn't work!" comments. Which can't be argued if they only make everything the same size...
Guitar neck pocket width is the very first thing I will change if I get elected God, at least as an option. Big frets + narrow neck + wide bridge doesn't work right, which is why even Fender went over to "modern" string spacing on the newer bridges. I would prefer a neck that got wider towards the bridge but NOT wider at the nut too; oh well.
