Hi , I saw this add on Kijiji, a local trading website for the region of montreal, canada Basically, this guy is selling me this BC RICH MOCKINGBIRD P7, a 7 string guitar for 100 $ because he modded it with a boost but he is taking it out.

What do you guys think of it?
Is the guitar good for playing some behemoth and some drop tunings?
Is it a steal?

thanks guys
