It works really well but generally with a tighter sounding amp. or an amp with an already controlled bottom end. All it seems to do is enhance your tone rather than colour it. The archer is the tighest klone I've tried and actually seems to get tighter as you add more gain to it, I can't figure out how but the controls play off each other. This leads you to dial less in on the amp end. For this video we used the exact same amp settings to make it a level playing field.
