I have a friend that swears by the Tonerite.
But the first thing everyone does after using one is change the strings.

Some guitars sound marginally better as they age.
Some sound leaps and bounds better.
I can give you anecdotal evidence of both things.
I do know that every one of my guitars sound better to me now than when I bought them.
I know that seasonally they change.
I know that some guitars are very picky about humidity.
I know some sound better at 40% than they do at 60%.
I have another friend that has a Collings that needs to be played for ten minutes before it is at its beat.

There are a myriad of factors that affect guitars. And how they sound.
The best part of this jourey is figuring out what makes YOUR guitar tick.
