The Bartolini NTBT 2-Band EQ Preamp Module brings advanced tone control to your instrument with its independent Bass and Treble adjustments. It delivers clear, transparent sound with powerful output and minimal distortion. The preamp includes an adjustable gain trimmer that allows you to enhance the input signal by up to 12dB, making it ideal for matching levels with other instruments or optimizing performance with level-sensitive effects. Bartolini has designed the NTBT with internal shielding to prevent electromagnetic noise, ensuring pristine sound quality. Additionally, internal filters block unwanted AM and FM radio signals from the input.

Crafted with professional double tin plated pure copper wire, the NTBT features durable semi-rigid insulation, which keeps the pre-stripped wires neat and protected in your instrument. Installation is simple; connect the EQ band wires to 50KOhm linear potentiometers, along with the volume control, battery connection, and output jack. For added convenience, pre-wired harnesses are available to facilitate upgrades. The preamp operates with a single 9-volt battery or two 9-volt batteries wired in series for 18-volt operation, providing an extra 6dB of headroom without affecting tonal quality.
