epiphone limited edition custom shop sg with flame top and gold hardware. the tremolo bridge does not require any mods at all. It fits over the tailpiece studs. it works great and the guitar stays in tune well if properly used (not designed for diveboming or radical use) similar to a Bixby but no extra holes or routing. the knobs are solid metal knurled set screw type. the weight and mass of the bridge and the knobs give the guitar the right weight for proper balance and add to the tonal resonance. these sg's are normally neck heavy. it is setup nice with low action and dead on intonation. the neck is what I would call 50's profile (not slim ) it gives it more stability than a slim neck. pickups sound great ,everything works good,. this is a solid ,stable , good looking and great playing axe.it is used and has normal wear but still in good shape with lots of fret life remaining. 250 cash/firm includes a nice plush thick padded good quailiy gig bag (pictured) I will also include the original tailpiece and it's real easy to take the trem off and put it back.
