I bought 2 in 2015, I think...an SCB6 and a DC600. The guitars played and looked ridiculously great! The sound, though...they lacked sustain, almost at all, and I ended up finding that my LTD H400, which cost me $350, sounded and resonated a million times better than my 2 $1500 guitars. It was very disappointing.
Ended up trading the SCB6 for a Gibson Gothic V shortly after getting the DC600 because it kept sliding off of my leg because the lower horn was a little on the short side. I have this problem with most single cut guitars.
I traded the DC600 to a buddy of mine for a 300 blackout AR pistol build. While the tone on both guitars was somewhat lacking, the tipping point for me on the DC600 was when I went to swap the Kiesel pickups with Dimarzio Dominions. Turns out, they used different length pickup mounting screws for the bridge and neck pickups. Ended up screwing right through the back of the guitar when adjusting the neck pickup height. Ended up having to repair that. Carvin did say they would fix it for me for $100, but when I initially emailed them, they said they do not use different sized screws. Then I sent them this picture, and they never addressed the screw size issue after that, just offered the repair.
Anyway. Sort of done with that company. The way the guitars sound and respond just make them not worth it to me anymore, no matter how much I wanted these guitars for YEARS before I was actually able to buy them. I will not purchase another.
