BB-04 Black Box - Stereo 2 Channel Plug-In Volume Control

BB-04 - Plug In Volume Control 
     This "Black Box" is a small lightweight 2 channel passive volume control unit that simply plugs right into the endpin jack or output jack of your guitar. It is designed to work with virtually any acoustic or electric instrument that has a pickup system, but that lacks volume controls.

     The BB-04 provides volume controls for two separate input signals and the choice of either stereo or mono output from the unit.      

Technical

     The BB-04 provides for two separate inputs via a 1/4" stereo TRS plug. It also provides the ability to select either stereo output of the two signals or mono output of the two signals with a small slide switch located on the circuit board within the unit. The signals feed out of the unit through one 1/4" jack.

     The volume controls are 500k audio taper pots. The unit is housed in a rugged ABS box. The "Black Box" measures only 3" x 1 1/2" x 3/4" (80 x 40 x 18 mm) in size. Weight: 2 ounces (55 grams).
