The bass response was different with the Harley benton too. On that hammer-on / chug riff. Might be my crappy old phone, but it seemed more "chewey" for want of a better term.
That's interesting. The Harley Benton on it's own is the weakest amp I own... But it also responses the best with pedals, boosts, distortions, via the effects loop, etc... The Harley Benton loves all pedals.
