B-Band A3.2 Acoustic Guitar Active Preamp
New for 2004, the B-Band A3.2 presents another step in the evolution of B-Band preamps. The A3.2 replaces former A3 and 3Tone preamps. The A3.2 offers a new 4-band "graphic" EQ design using rotary linear potentiometers for greater range. The EQ controls are cut / boost bass, middle, treble and presence controls.
The BBand A3.2 is a single input sidemount preamp and works with a choice of either UST or AST.
The B Band A3.2 kit comes complete with all hardware for installing and includes a high quality endpin jack with battery power switch. The new hold-tight 9-volt battery clip holds the battery securely so that it will not come out accidentally while handling and is adhesive-backed for easy installation. For quicker battery changes, an optional side mount battery box can be ordered. There is also an optional wood faceplate available.
