Hmmm  11th graders are at the know it all stage of life but here's the opinion of a Hendrix fan and audio collector of 35 years and BTW, good luck with the kids; Vai, Malmsteen, Steve Stevens, etc.. are all technically brilliant (and the kids will find Jimi eventually).

We listen to Jimi thrash and bash torture the poor guitar but we forget that in 1967/9, the electronics were exceedingly primitive.  There was a cord connecting the amp and guitar that corroded and failed, guitar necks warped on the way to the next gig, Fender Strats stayed in tune unless you played them, and the stacks of amps we oggle in the videos were a relatively new invention that blew apart, failed, and tubes (what's a tube and how old are you anyway?) burned out constantly. Add a couple of pedals and 3 microphones to the mix for a complete electronic nightmare.  A successful gig with no equipment failure(s) was almost a miracle and performers did not have an endless supply of tricks from endorsements.

I would turn the kids on to most of the Axis album and watch the kid whose eyes glaze over...he/she understands guitars.

Good luck with the rascals, they're a tough audience today!
