Not posting in the Pod HD thread since it's been basically abandoned. So, it seems that after all these years of owning a Pod HD500, I can't get high gain tones to sound fully right in any possible way. The general tone is ok, but on single note stuff and especially on any kind of palm muted stuff (may it be chords or single notes) the actual "tone" suddenly disappears and I'm left with a clean-ish signal that's basically just an hollow "woof" of low mids plus noise, missing any body to it. I'm used to use the least amount of gain as possible but I tested and this seemingly happens at any level of gain, both with guitar-same and guitar-variax, and even with both OD and compression engaged pre-amp. I usually use the FBall sim. I just don't know what to do, any advice?
