2004 Music Man Sterling Desert Gold

Just picked this up used at a local music shop. Serial number is F10000. I can’t find any manuals anywhere. What does the switch do? This is my first MM bass, I came from a Fender Jazz and an Epiphone SG. I ordered an Orange Crush 100 amp should be arriving tomorrow. Can’t wait to mess around with it. I like a distorted heavier sound, I’m sure I will be able to achieve that. Anybody have any links they can point me to regarding what all the switches/knobs do?
