One thing I have always noticed when watching live gigs, or playing them myself, the less distortion one has, the better you can hear everything. Most Funk or Classic Rock bands I saw had a very transparent sound, but it also always depends on the location and the sound technician the house provides I guess. I have also noticed that running the amp through the Sound System of the venue oddly adds further distortion to the sound, so I guess that justifies the argument with using less gain and bass. I played a big gig with my ex Pop Rock band once, only using a Tubescreamer for Overdrive through the clean channel of a Marshall, and I wasn't satisfied with the tone I heard on stage, because it had too little gain for my taste. Then I saw the Video a friend of mine did and the sound was perfectly fine, the TS had more gain through the Sound System then I heard on stage. Explanations?
