Hi John,
There are 2 volume controls, 2 filter controls (these are the Alembic tone controls) and a 3-position pickup selector for each pickup. These offer off, on, and bright. If your guitar has LEDs, there will be an on/off switch for their operation.
On the inside of the guitar, you'll notice a small trimpot on the back of each pickup selector switch. Change this and you will change how bright the bright setting is. Experimentation is encouraged!
Use the filter controls to set the highest frequency you want to hear. If the guitar is too bright sounding, turn the filter control counter clockwise to reduce the extreme highs.
The output jack is a long frame jack with welded palladium contacts. These are the same connectors used on old telephone operator switchboards, rated for much more use than it will ever see in a guitar.
Enjoy and please let me know if you have any other questions.
