Hi guys, I'm a total newbie as far as electric guitars go - just bought a guitar + amp on Saturday. I've been messing around with the settings on my new Laney LX20D and I find that the volume control does not just increase the volume, it actually changes the tone that I hear from the speaker. Is this a feature of cheap amps or am I just imagining it? Is it better to keep the volume at full and listen through headphones to get a good tone? Also can someone tell me what the tone control on the guitar does - does it vary the relative amount of bass::treble in the output signal from the guitar? Thanks a lot guys, Amit.
