I wonder if that is dependent upon volume and playing style. And do you know what rectifier tube is in your stiletto? The Plexi 51 came with a JJ. I have read accounts by some people saying that some particular rectifier tubes do make a difference in sound, where others don't. And then other people say that the choice of rectifier tube has almost zero effect on the sound. Guitar playing is all pocket draining madness I tell ya. On another note, I'm reading that new capacitors might take around 100 hours to break in. More madness.
