[p]Turn it up! I think this primarily applies to tube amps. And the best thing to do it turn all the knobs to 50%, turn off any effects, turn your guitar up to 10. Then start to play. Turn up & down the volume & the EQ knobs a little bit at a time while playing & listening for more or less fullness or richness of sound. This is obviously going to vary from person to person depending on what your goals or desires for the guitar, music & style you want to play.

This guy does a pretty good job of demonstrating the process in a general way.

This is a little harder to apply to a digital or modelling amp. Because those are explicitly designed to always have some virtual version of a "sweet spot" coming out of the amp at any volume. That's the kind of the purpose of the design.

But the thing to listen for with a digital amp is how it interacts with the speaker cab that it's pushing.

The only thing I disagree with him there is that he starts with the master on 1 & never turns it up beyond 3.5.

If we're talking about real tube amps, then you should turn it up to at least 5. Otherwise you are aren't using it to do what it what designed to do. That's why large amps are so impractical & so many small combos & digital amps are more popular nowdays.

It's also why many classic songs & amps were actually recorded with smaller tube amps cranked to the max instead of stacks used to perform the same songs live.

Hope that helps!
