i have heard/read rumors of both clapton and paige having used champs and other small amps in recording sessions. i do know-since i saw it, and presume it was 'on'-that a lineup of small amps was behind jeff beck in the video for the les paul tribute.
premier guitar put the 'nos' champ as one of their 'gear of 2010' items. i have avoided playing the grand (literally) thing; i don't want to hear if it sounds better than my $130 'returned to musician's friend' wonder. i guess i don't care....
i was yakking with a radio shack manager acquaintance who plays guitar...i told him about my experiences with the 22 Caliber...and he said he dint think that those in the audience at a live gig could 1. tell a difference in a good digital vs. an average tube amp; 2. could not tell a difference if the guitarist was 'in sync' volume wise with the rest of the band and 3. did not care what amp the guitarist was using. gear chasing is, perhaps, its own reward? the journey is the reward (to quote steve jobs)? there is no reward? except on the posters at the post office for my apprehension. time for a tranquilizer to get rid of the apprehension, i suppose

really, this leads me back to what those who are wise often say 'somewhere in print'....ya gotta find your own sound. you have to find your own rig. if you listen too much to others, and don't weed out the bs from those who actually know anything, and/or care to help you...you wind up chasing your tail. it really doesn't matter what gear you use, if you like it...it sounds good to you..and it fits in the mix. which leads me to that article on cigar box guitars and the north mississippi allstars.
in psalms, i think the preacher says something like 'marketing...all is marketing. all will turn to dust and fried transistors...nowhere under the sun is a guide to real tone.' *dodges lightning bolt*
