Welcome to GT !
Tone knobs, well it depends on Werther they are positioned before or after the preamp. Passive EQ before the pre will have a huge influence on volume, distortion ans EQ, pulling down your mids on a blues crunch amp with EQ before the pre can really clean up your tone.
However, it also depends on the amp and the way it is designed.
Death Metal / mid 80s metal usually relies on scooped mids and pumped top and bottom end which I cant say I'm that fond of.
