Boosting the sound of my highest notes?

The compressor advice was good, the vibrato advice from Greg was great.

And balancing your pickups output is important too. Play a note on the bass E string and then play a note at the same fret on the high E string. Chances are the bass note will sound far louder. So you usually have to either raise the treble side a little higher, or lower the bass side of your pickup. Takes a few adjustments, but you want an even output. Don't worry if the pickup sits at an angle. It is not important how it looks, it is important how it sounds.

Also try an EQ pedal, boost the upper mids. These are the notes high on the fretboard. An EQ pedal will bring these notes out with power.

Do all of the above and it should sound great. :D
