Ibanez is a major creator and contributor to the pool of available guitars, amplifiers and even effects pedals
Ibanez began before World War II
largely in Spain, but Ibanez was only truly recognized after the 1970's. In the 70's they came out with some Fender and Les Paul copies which often sounded as good or better than the real things but were priced much lower, making them popular among those who couldn't get their hands on the better equiptment.
Pretty soon some guitarists that were poor and played Ibanez like George Benson
, Adrian Smith
and Paul Stanley
started getting real famous and making big bucks. This really helped Ibanez's reputation and business. Soon Ibanez really began innovating and coming up with great products from jagged destroyers to the more modern RG Series guitars both originally made for the insane lead guitarist in a heavy metal band.
Ibanez also created the legendary TS-9 Tubescreamer
effect pedal deliverying very tubey distortion
, still considered today to be the holy grail of distortions and overdrives
Today Ibanez is played by guitar heroes like Joe Satriani
and Steve Vai
and is bigger and better than it ever was, still expanding vastly with a new Tone-Lok
pedal line-up, the S series guitars and much more. They are now largely based in Japan.
I myself own an Ibanez S-Classic
SC420, and having a decent amount of knowledge as a guitarist can tell you that Ibanez makes some of the best guitar and effects there are and at a very affordable price.
