Here's some questions maybe you tube techs can help me with. Is a preamp with 5 tubes necessarily warmer sounding than a preamp with two tubes (ex. ampeg svp-pro vs. aguilar 659) or does the circuitry invovled play an important role? Is there a point of diminishing return with tubes? For example, if someone were to make a prototype of an amp with 50 tubes and all the bells and whistles, weighing in at only 20lbs, would we all want to buy it? thanks, guacamole I never got welcomed here at talkbass like all the other newbies, where did i go wrong?
