oh a dictionary on guitars here
i'll add something extreme.

Model: MMM1 Mike Mushok Signature *haihs discontinued already, he changed to PRS*
Brand: Ibanez
Type: Electric guitar, baritone 28" scale
Nickname: no need nicknames, the sound speaks for itself
Style: for any heavily downtuned music, fits for some jazz too

Mike Mushok is the guitarist in Staind..
He usually uses weird tunings and custom string gauges in their music
Some sounded pretty mainstream, and some just way heavy..
He got many custom guitars and prototypes..
I think he used a 7-string for the song "It's Been Awhile", RG1077XL if im not mistaken..

bought this 4 yrs ago as my 1st guitar..
hard to play at first, ppl usually start off with acoustic/classical..
with a slight downtuning, u can play it like a 7-string..

for specs, its a neck-thru guitar.. massive sustain..
string thru body construction, 3 piece mahogany-bubinga-mahogany neck with mahogany body
gibraltar custom bridge *not a custom anymore, also on other latest ibanez models*
super 58 custom wounded pickups.. dunno its okay for metal or not, but so far it sounded great
rosewood fretboard, 22 jumbo frets
chrome hardware, mahogany oil finish
all the while i was playing heavy stuff
and now i need a standard guitar to play more music
