Battery Replacement
•
Battery Life: The booster preamp in the bass requires a single nine volt battery to operate.
Plugging an instrument cable into the bass activates the preamp, therefore leaving the cable
plugged in when not playing will drain the battery within a matter of days even if the black
toggle switch is in the preamp bypass position. Battery life will range from a few months to over
a year if the bass is unplugged when not in use.
•
Battery Cover: The round Plexiglas cover (which looks like a gas cap) covers the battery
compartment. It can be removed with an allen wrench of the appropriate size (included with
accessories).
•
Battery removal: The battery fits snugly into the bass body to eliminate any vibration. To
remove, gently pry the battery loose using a thin metal object like a butter knife or small
screwdriver.
•
Passive operation: The Air Force Bass is designed to sound its best with the booster preamp off.
If the user never activates the booster preamp, the battery is not needed. Without the battery
in place, the black mini toggle switch will act as a master on/off switch.
Care
•
Cleaning: We do not recommend use of any wax, polish or cleaning products. The bass should
be wiped after each use with a soft cotton cloth (like an old t ‐ shirt).
•
Temperature Control: Whenever possible, keep the bass from extreme temperature conditions
and avoid rapid temperature changes. When transporting the bass, leave it in the case after for
at least 30 minutes after arrival to allow for a gradual warm up or cool down.
•
Humidity Control: Humidity control is helpful, but not as important with a solid body instrument
as it is with an acoustic guitar. In moderate climates, the bass can be safely displayed outside its
case.
•
Strings: Roto 77 bright flatwound strings are included with the bass. They will last indefinitely.
Experimenting with different strings is a great way to change the tone of the bass, but may
require adjustment of the bridge and/or truss rod. See the links below for information about
how to do your own setups.
•
Finish Repairs: Some folks pay extra for a guitar with a “road worn” distressed finish. If you
prefer to keep yours looking new, minor dents, dings and paint chips can be filled in with an
automotive type touch up paint.
