All this guitar smashing causes me musical pain. I started playing guitar three weeks ago and have been playing day and night nonstop since. I'm going to wait 6 months before buying a guitar of my own just so I'll appreciate it more when I get it. To start a guitar collection of sorts--the idea sends shivers down my spine.
It's probably just a phase, this over-reverence for the physical instrument. In my current mindset, it's just strange to see talented musicians who have no respect for their outlet. I suppose if I were rich and famous, I wouldn't care as much. Personally, though, I'd never smash my guitar. I'd spend all my money on exotically custom drool-inducing instruments. Experiment around and stuff in ways I otherwise couldn't.
As for nickleback (you know, the subject of this thread), um... don't suppose they smash their guitars? Actually, that'd be really funny.
