.also note that the guitar amp world soldiers on using a lot of tubes, with new amp designs (and reissues of old amp designs) coming along all the time. Don't fear the tube...they simply make music sound a lot like it's supposed to.
While I tend to agree with most of your posts on this topic, this old chestnut has to be surrendered to the trash pile where it belongs. I play around with the guitar only, but I go to a hell of a lot of live shows. Most recently Dweezil Zappa playing all of "Hot Rats". Modern guitar playing involves a lot of intentional distortion. Every hot guitarist with chops relies on a ton of effects pedals in addition to the intentional distortion produced by the tubed stacks. If you happen to get the Sweetwater catalog (which I strongly recommend for any audiophile to see the overlap with our hobby in terms of speakers, mixers, DAC's and lots of Manley pro gear on offer too), you will see that there are more pages devoted to effects pedals than any other musician's tool under the sun. It is simply amazing. Btw, this makes me think of Raulgas with his stupid motto "musics and not distortions" [sic]. Well guess what, a lot of recorded music contains a lot of intentional distortion including even classical music, but mostly rock and modern jazz.
