I’m forever trying to get more savvy with my electronic band gear. Much still has me head scratching, such as:
With tube amps and rock and blues, I understand the concept of over-drive using more gain for getting that desired growl on guitar and blues harp and such
But why do companies put both master and gain knobs on acoustic guitar solid-state amps designed to have a lot of headroom and a clean-as-possible signal? Why not just one volume knob?

It is used as well on mixing boards, so the concept is ever present. This is the way I understand it. Gain is the level of the signal in. (Think of the amount of fuel fed to a carburetor from a fuel pump). Volume is the level of the signal out...master volume. (The amount of throttle to open the carb and make the car go faster). You don’t want the gain too high to cause distortion (fuel pump over riding the carb and flooding), nor do you want the gain too weak for the amp stage unable to amplify the signal (starving for fuel). You can’t amplify a weak input signal, nor do you want the input so high as to distort. I hope my concept is correct....if not, you can still use it to diagnose fuel pump issues.
