Ummm... I guess my original point was that all else being equal (quirky guitar, my questionable technique, etc) I DO hear a difference in how the 3 above-listed amps respond to 'adverse' conditions. It's not even that subtle, really. Refined question being: what are the amp-related variables that contribute to the accentuation/attenuation of the best & worst I get from the guitar. We're kinda getting there :-) deviations from original topic are fine by me, that's healthy dialogue.
