I do need to experiment more with the controls. I haven't understood the best way to do that, and frankly, am not sure of the sound I'm looking for, so I have been a bit lazy! And then, I'm not sure I hear sound differences that well. Guitarists on Internet sites make tone changes, and after doing so, I don't hear it. The tones sometimes sound the same to me. I'll work on alot of the ideas I've received from you and others on this thread. Thanks!
