Talking about the midrange ones. How are these, build wise? Are they actually mahogany, or are they like Epi's where I've heard they can actually be different woods. How would the build quality/feel, compare to a faded Gibson?
They are mahogany and have a set-thru build. I've played one before and it had a good feel and a great sound for like metal/rock thanks to the EMG 81/85's they have.
i have owned one and i loved it. i think it was better than my epi les paul that i put EMG's in. im fairly confident in saying you would not be let by this guitar.
