This is a mint Eastman AR603CE-15 Archtop Electric Hollow Body guitar. This is a more upscale Eastman model that features a solid hand-carved Spruce top as well as a hand-carved Mahogany back and sides. All solid construction along with the Kent Armstrong top mounted PAF gives the guitar a lively and warm amplified tone. 

The 15 inch lower bout and 2- 3/4 inch body depth make the guitar very comfortable to hold when standing. The Rosewood fretboard is well constructed. The Mahogany neck has a C profile with a 1-3/4 inch nut width, making the neck slender and very easy to play. I like that Eastman uses a lacquer finish instead of a polyurethane finish. Lacquer just seems to let solid woods resonate more freely.

I find that the top of the AR603CE is sensitive enough to use light gauge strings on. I’ve been using Thomastik Infeld .013, .017, .020, .027, .037, .050 with a wound G string. Acoustically, the sound is louder than other small body archtops I have played, but the shallow depth probably contributes to a brighter, more acoustic sound than a full sized acoustic archtop. Plugged in it has a very warm, clear jazz guitar tone.
