My Peavey Wolf is an amazing guitar- perfect for me.
I was so excited when the HP2 was announced. They used NOS parts so this is essentially a Wolfgang. I can confirm this as I have them side by side and the guitar is near identical. The differences to me are the pickups are not the same. The HP2 allows for split coil options, so they voiced the pickups to be more friendly for this new diversity of tones. As far as straight humbucking sound, this means it is more 'normal' or flat/less hyped compared to the Wolf. Good pickups, but I like the Wolf better. Plus I don't use the split coil, so that change I do not prefer.
But the curious part is the aging- the Wolf feels amazing, and although it arrived virtually mint, I think the aging really added to the great feel. The HP2 feels the same - but not because it has this 'new' feel. I am sure with lots of play or 10 years go by and it will have that cozy feel. Your comments above kind of confirm that for me.
I actually have the HP2 for sale as I am moving this summer, which means my band is blowing up and I need to free up cash. But if one loves the Peavey USA Wolf, one should really look into the HP2. As soon as they ran out of NOS parts they stopped making them, but there's still a bunch available online as this was recent.
