Bartolini NTBTG/918 Preamp Module, 2-Band EQ with Pre-wired Gain Trimmer

Independent bass and treble control with adjustable gain.

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.

Like all of Bartolini's preamps, the NTBT is internally shielded to reject electromagnetic noise and includes internal filters to block AM and FM radio on the input. Bartolini set the standard of fully sealing the sensitive electronics. Bartolini use professional double tin plated pure copper wire with durable semi-rigid insulation. This ensures the 5 pre-stripped wires don't flop around in the cavity and the wires don't cut through the insulation over time.

Installation is straightforward by connecting the EQ band wires to your 50K? linear potentiometers along with volume control, battery connection, and output jack. Or you can use one of Bartolini's 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.

These preamps have a built-in equalizer (EQ) that lets you quickly adjust your frequency response while they also isolate your pickups from your output jack so the voice of your pickups is not negatively affected by your cable, effects, or amplifier. Every electronic component that directly connects to your pickups will diminish their performance and weaken their output.

Preamps solve the problem by strengthening the pickup signal and limiting the components connected to the pickups. Some of Bartolini's EQ preamps also let you boost your pickup signal so you can balance the output with other instruments and control the signal to your level-sensitive effects like overdrive, compressors, and envelope filters. The built-in EQ helps you control how you fit into the mix with other instruments and compensate for musical changes while you are on stage or in the studio.
