Mac,
I had that nagging thought too, in the back of my head. Not that *I* would *hear* what you hear, but that so many shows are actually using sampled libraries for an 'on the cheap' studio production.
If that were the case then I would point you to one Mr. Cody Westheimer as a possible culprit.
There was an uncredited appearance by 'Brand New' singer/guitarist Jesse Lacey as the guitarist in the band.
