I've read that Hendrix had his amps retubed with 6550s, replacing the original EL34s, which would explain why his cleans sounds brighter than the typical Marshall clean sound.
Wasn't it KT66's that he used? A JTM45/100 with KT66's was the amp he used on Experienced.
Tom - I've worked out the mod that gets the Slash/AFD amp from an ordinary Marshall, it's not really anything that advanced. It's like a tweaked JCM800 when the extra gain stage is engaged (if you make it switchable). Personally I prefer the Silver Jubilee sound.
Personally my favourite tones are Yngwie Malmsteen's, Eddie Van Halen's and Jimi Hendrix's. Those guys had some awesome Marshall tone going on. But my overall favourite tone is Bareknuckle VHII's through my Plexi that I've tweaked a lot to make it perfect for what
my ideal tone is. Unfortunately, that killer tone has yet to be captured through my recording clips, but I'm working on it
