Can't really tell you exactly as the only Carvin/Kiesel I have ever played is my own DC727 I got in 2010.Aries vs dc727?
I have an Aries 7 with the thinner neck profile and I really love it. It's a mainstay in my collection.
A guy on FB has a DC727 for sale for an attractive price that looks nice (carving).
How do those things feel compared to Aries? Much thicker neck? Thinner?
Big difference is it's neckthru and has two humbuckers.
Extremely stable and well built instrument. It (sadly) went over a year in its case, unplayed, at one point, and when I finally took it out, it was still decently in tune and the neck hadn't moved much at all. It survived a full Canadian winter like that.
The fretwork is pretty great, and the neck shape feels nice. Just as Max said, medium sized, full C shape that's nice to grip. Very inoffensive.
Mine came with C26 humbuckers, and I replaced the bridge pickup with a D-Sonic 7. Not much had to be done to it except drill a new hole for one of the mounting screws, but it's a tight fit. The C26s have two screws on one side to prevent the pickup from rocking back and forth within the cavity.
