I can't believe it's been a decade either Mike. I was ogling 002 and 003 ten years ago and bought them 8 years ago!
I kind of like the fact that all three necks are different, 002 is still in Drop C, and the chunky neck feels good for those types of riffs. 003 is thin and wide and promotes thumb behind playing and 013 is a pretty standard thinner Strat shape. Definitely the most familiar of them all. Overall my favorite profile is the C on the Hot Rod AVRI 62 Strat, a little chunkier than modern, but slimmer than 62. I've debated replacing the neck on 003, but the flame on the current one is killer!
As to the mods, the nut is very nice, and locking tuners do make the change a breeze. I'd like some brass tuning keys to tie the look together, but I'm not sure if that will happen. I'd also like to hear a C5 in it, but I think for now the Single is going to remain.

...and Marilyn may have to make a return too.
I really like that white strat style D'Avanzo you built...
I'll PM about the logo...
One more thing, what do you think about polishing the brass on these types of guitars in general? I like how this one is going toward natural relic with raw brass, nitro and maple, but like on 002 everything is pristine except the volume knob. Is that the look or should I polish it?
