Just got a LA10 for practice purposes. I am curious if the distortion on open 'E' and anything lower on the 5th string is typically the speaker?? I have not learned enough to know if the distortion I hear on the low notes is the speaker or can it be the amp and/or cab? I love to experiment with my gear and if I thought it was a speaker then I would experiment by putting in another one. Thanks...Gus My wife says that I need adult supervision.
