The NTBT is a 2-band tone control preamp with fully independent Bass and Treble controls. The voice is clear, transparent, and strong with ultra-low distortion. The NTBT features a pre-wired adjustable gain trimmer which allows you to boost the input signal up to 12dB (4X) to match the output of other instruments or tune the output to drive your level-sensitive effects. Installation is straightforward by connecting the EQ band wires to 50K linear potentiometers along with volume control, battery connection, and output jack. Or you can use one of our pre-wired harnesses to make your upgrade even easier. The preamp can be used with either a single 9-volt battery (9-volt operation) or two 9-volt batteries wired in series (18-volt operation) for 6dB extra headroom with no tonal change.
