I got one second hand last year, like yours, but natural and with pickup (aj500me). Wish I'd found sunburst though. Great guitar, and LOUD! Really served me well in the Zermatt Unplugged festival. Amplified the sound is so so, but to me that is true of a lot of electro acoustics. My thinking has since become that if I'm going to amplify an acoustic guitar with anything but a microphone, it really becomes an electric guitar, and I might as well use an electric that was designed with amplification in mind.
Have fun with that guitar, those Masterbilts are really great!
