parallel posting ...I've got my amp set where having the tone and volume on my guitar both all the way up is searingly bright.
Not every amp and not every guitar can do this.
So I roll the tone back a little bit - and there's my crunch sound.
Roll the volume back - there's that mellow clean sound
Roll the volume back and push the tone knob up - there's that sparkling clean.
Turn the volume and the tone all the way to zero - there's that part of the song I don't know how to play but want to pretend I do
