I've been looking at getting something radical to get a new sound and am seriously considering an LGM Leviathon.
Spec is as follows.....
- 8 strings
- 36 frets (a whole extra octave to play with on the upper end a an extremely deep crunch off the lower F#)
- scaloped maple fretboard
- polished maple neck
- alder body
- Seymour Duncan Screaming Demon 8's pups - specifially designed to be mud free on the low end
- fixed bridge
- black hardware (don't like the gold option)
- Either deep black or 'Arcticburst' finish on the body and headstock (leaning toward the arcticburst but with a maple fretboard).

(the 36 fret 8 string option can be seen on the last two on the page - I prefer a regular maple fretboard than the exotic woods myself)

It's pricey but I've had a good year so I'm thinking of treating myself:-) Anone ever try one or know anything about LGM? I've only heard good things myself so far.
