I think the guys know that a large percentage of their fanbase is made up of musicians, and many of their fans are not. I think they do a pretty good job of speaking to both audiences, although it's a little hard for me to tell since I am a musician and have some techinical knowledge. When JP starts talking tech about his guitar rig, I can follow some of it even though I don't play guitar, just from what I've picked up over the years. I'm never going to apply any of it, and I don't even follow a lot of it, but I still find it fascinating. I just figure he's talking to guys who do understand it.
I don't expect them to dumb everything down; that wouldn't be fair to fans who actually want more technical detail. I figure if you play -- keys, guitars, whatever -- then you can follow what they're saying. If you don't play, well, some of it's gonna go over your head.
