PODs have been a signature sound for Fear Factory's guitarrist Dino Cazares. I remember he started using it since XT series, getting a great sound for their Digimortal album. Apparently, he's been using XT, X3 and HD until he gearwhored into Axe FX :D It's been almost 2 years since I own my POD HD500. I wanted one since XT, and just 2 years ago I had the money for one. I remember when I first used it at a Metal Fest last year, in an open place, good sound for the venue, my patches weren't the best (Just simple amp and wahs or whatever I used, but no mid-EQ or Screamer). This guy from another band came with a Mesa Boogie Dual Rectifier. My band was playing before, and I liked the sound of my guitar (Which by the way, distorted patches use a Treadplate heheh). After our show, I sat to listen to this band and thought "He's really going to kick lollipop with that Mesa", but to my surprise, it didn't sound better than my guitar. As long as you can get a decent unclipped sound from the POD, I think it sounds great both live and in studio. Of course, it'll never sound as good as real gear in my oppinion, but there's unlimited possibilites in these boards. You have like $30,000 gear worthy in it, something hardly achievable in real life. It's not like your going to use everything, but in time, you know you can experiment with them and see what it comes out. Edit: By the way, my POD is coming out through the Power Amp of my transistor amp head and 4x12" cab. I've tried it through the PA of our rehearsal place, but I never got it to sound good, so I never ventured into trying it direct to the PA in a live situation.
