I use from time to time that HP for three years. I begin to have tried a lot of HP 12 inches just under 10 inches. Which is nevertheless a format that I find appealing. I bought it secondhand HP to see what it looked like. Performance and proper it is not too expensive.
I think its level:
On a clean Fenderien to play alone is rather faltteur see very flattering, it lacks a bit of bass.
On a clean Fenderien with other musicians, it is sorely lacking in midrange, treble means that it is not really top.
If we add the distortion, then there it gets rocky aggressive and not at all pleasant to my taste.
HP not versatile, you're a fan of a clean slammed fender, go. You want the distortion, ben try something else.
If you want to hear and compare what happens, I made some small sample there some time with an SM57, nothing great but if it can give an idea ... https://sites.google.com/site/zoubirocker/comparatif-hp
