yeah kinda of wierd about the your SG is it being a fender but i would definitly say a good deal
i have a 70's reissue strat which is amazing and a epiphone SG which i also adore SG's have an amazing feel and vibe. but my strat just screams malmsteen haha.

isnt it a truss rod that you adjust in the neck because when i think of tremlo i think of a tremlo bar being a whammy bar but i dunno

and would that happen to be a bently acoustic in the background my friend has a black one which is amazing looks like same headstock
