Having decided that I was not interested in lugging around a gargantuan tube head, the search for my next bass amp head had pretty much come down to Mesa or Genzler. I mean, if it's not an SVT, why even consider Ampeg, right?
But then, I got a helluva deal on a PF-800 with an SVT-410HEN. I initially thought I could just flip it, and get what I "wanted"--but then I tried it out... I was seriously blown away by how good it sounded. I knew right then and there that I was keeping it. And when I looked at it a little deeper, I realized that it had every feature I really wanted: 800W @ 4 ohms, 2 outputs (w/ speakON), mute, built-in compression, effects loop, simple 3-band EQ, DI out, and even an Aux In and headphone jack!
Sure, compared to the newer micro heads, the PF-800 is certainly on the larger and heavier side. Yet at under 12 pounds, it is still very easy to heft and transport. But that leads to my one complaint: given that heft, I think Ampeg missed the mark a little by making these heads so unfriendly for rack-mounting. I've seen a couple ingenious owners have mounted it to a shelf, and it looks fine, but it's still a miss--these heads should have been designed to easily accommodate rack-mounting.
Still and all, the PF-800 is a great sounding head with a TON of features and a price that makes it an absolute bargain.
