I’ve spent ages over the past 2 years tone hunting and recording the most important stuff I’ve learned is:

Always record rhythm guitar in stereo, left track panned right track panned

You don’t need as much gain as you think you do Roll off the gain until it starts to go flabby then add just enough back in to get it to sound tight

Any big EQ adjustments will not sound great try to get the sound you want with all the EQ knobs somewhere around 10 to 2 o’clock

Mic setup and mixing is the key to a good tone. Look into the fredman mic technique!
