and american tone?
I always just thought Marshall=British and Mesa/fender=American.
That's horrible generalization, but that's how I've always seen it.
I don't think that's all that far off. I always percieved the British tone to be alot darker. As was said, Clapton in the BluesBreakers defines, for me, the best and most obvious points of what it was; warmer, darker, thicker, even muddier at times.
The "twang" to me is the all-American sound; a Telecaster into a Deluxe Reverb or Super Reverb or even a Twin. To me that's the sound that defines "American" for me. There's lots of mids and lots of highs and when you crank it the tone takes on a life of its own and smoothes out, but doesn't really get anywhere near as dark.
American tone: 6L6 or 6V6 tubes
Brit tone: EL34 or EL84 tubes
That's a start, anyway....
I tend to agree, I think the final definitions of British tone are Blackmore, Iommi, guys from Uriah Heep, Page, May. Some how that took that muddy overdrive and just made it sing so precise, so defined, with every note accented just right. And of course no body does British tone like Laney, sorry had to do this one guys.To me, the british sound is darker, thick, woolier, and even muddy at times, like you say.
