First, a clarification. One could fairly accuse me of sometimes posting about things that I could probably discover through trial and error, and while I am usually the type to do just that, I have already expended all of my autodidactic tendencies in another realm, and thus I am grateful to have the benefit of the expertise offered by seasoned persons here at recording.org. Besides, the responses to simple questions sometimes contain information that is unanticipated, yet highly beneficial. I have read before that guitar amps need to be driven hard and loud to sound good on recordings. But why is this so? Why would low or moderate volume be inadequate? Would amps driven at low or moderate levels not produce their own particular sound, that might be appealing in its own right? And, could a keen ear determine how loud an amp was run from listening to a recording?
