I've narrowed my next amp contenders down to these two. Zep, Skynyrd, Lizzy, Rush, Fleetwood Mac. I know the Rocca excels at these tones, and can probably get me into Maiden, Megadeth, Metallica, Van Halen territory with the right pedal. However, I'm guessing I'll have to kill my hearing to do it or invest in a Hotplate. The Hellcat has TWO channels with independent gain controls plus Reverb which are big pluses for me. No Hotplate required. My heart says go Rocca; my head says Cornford. I guess I'm hoping someone can convince me that the Hellcat can do all of the above equally well. Unfortunately, I've only heard the Guthrie Govan clips which are all blues/jazz/fusion tones -- I'm not into that. The reviews say it can do all this, but the Cornford seems... I dunno.. a bit refined and modern? Hope someone can help me out here. I need to make a decision soon, and I'm beating myself up over this. BTW, I'll be buying used. No chance of trying first. Thanks.
