Schecter Guitar Research is well-known among musicians for introducing some sweet horror-themed and gothic-style instruments; they've released guitar models shaped like coffins, and sporting names like “Damien” (which features inlaid flying bats on the neck) and “Hellraiser” (which isn't tied to the movie of the same name, but it's a pretty fine machine). I'll admit I'm rather biased, as I've owned a couple of their axes myself, but they might make a believer out of you too when you lay eyes on these horror movie editions to their Custom Shop Masterworks line.
The very limited collection (just so you know, several of these have already sold out as of this writing) features licensed artwork depicting several classic Universal Monsters, including Frankenstein's Monster (dig the stitching on the guitar neck... just like the big guy himself) and his Bride, The Mummy (featuring a very 21st-century naked lady) and a beautiful rendering of The Wolf Man.
Other models include official artwork from Dawn of the Dead (shown at top) and House of 1000 Corpses, with Sid Haig's Captain Spaulding.
Right now these beauties are only being sold by Drum City Guitarland in Colorado, mostly in the four-figure range (the Universal Monsters guitars had price tags between $4000-5000), so they're targeted at serious collectors with deep wallets... and they're disappearing fast, so be sure to check out their site pronto!
