That’s certainly a lot of firepower for one ad. This is Ibanez saying, “have we shown you our ridiculous stable of endorsers?” and commemorating “The Ibanez Axe Attack,” a concert held in conjunction with Winter NAMM ’93. I find no evidence that anything similarly branded has been held since.
It’s rather absurd to heap Steve Vai under “et al.,” but he doesn’t seem to be pictured. Those that are listed and pictured: Paul Gilbert, Joe Satriani, Shawn Lane, Alex Skolnick, Andy Timmons, and Reb Beach, along with the apparent rhythm section of Gerald Veasley and Simon Phillips. Someone played an arpeggio.
