For the money, 400 & up series vipers are great. I've put mine through HELL and they wont die. I've dropped, kicked, thrown, and flat out abused the piss outta my white one since the day it was bought new, and have only had t make one neck adjustment on it (and that was to change string guages).
Not to mention that my white 400 has one of the best feeling necks Ive ever wrapped my left hand around. (and even better since I shaved the neck. ). Even before I shaved it, it felt VERY similar (profile wise) to my old '73 Stratocaster. I guess if i were a "pro", a Viper would be "my" guitar, like a Strat was Jimi's guitar, and a Les Paul was page's guitar. Everything I ever wanted in a 2 humbucker "gibson-type" guitar, and looks cool to boot.
Whats great, is you can find used ones DIRT cheap . I almost bought a sunburst 400 series viper that needed pickups for $150.00. I wish I'd bought it now.
My Broe Jarrett has an ESP Standard seried viper, and the quality isnt much diffrent. (not $500.00 diffrent).
I wish they'd put out a Kirk or Pep signature Viper
phanboi gheyness, but I'd proudly buy one.
