The AG2PB/918 is a high impedance preamp for use with piezo or microphonic transducers. It features adjustable gain which allows you to boost the input signal up to 12dB (4X) while maintaining flat frequency response. It is less than half the size of a 9-volt battery making it ideal for instruments with limited cavity space. The AG2PB/918 provides a strong output signal and isolation from external equipment that may otherwise adversely affect pickup tone. It is often used to make a passive instrument active with very little effort. With only 4 wires to connect power, ground, input, and output it is a simple way to ensure your piezo-pickup instrument has all the power and isolation that it needs. The AG2PB/918 provides 2 independent high impedance buffers in the same space as the AGPB/918. This is great for separately boosting 2 pickups from a split piezo saddle, as part of an independent setup for individual string saddles, or to mix a piezo with a microphonic transducer. Individual gain trimmers per channel give you a lot of flexibility. Like all of our preamps, the Piezo buffers are internally shielded to reject electromagnetic noise and include internal filters to block AM and FM radio on the inputs. Bartolini set the standard of fully sealing the sensitive electronics. We use professional double tin plated pure copper wire with durable semi-rigid insulation. This ensures the 4" pre-stripped wires dont flop around in the cavity and the wires dont cut through the insulation over time. Either 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 double the (6dB extra) headroom with no tonal change. Both versions delivery clear and transparent sound with extremely low distortion.dual channel buffer preamp for electric bassclear transparent sound with very low distortionsuitable for passive high-impedance pickups (piezo or microphonic pickups)two independent buffer channels to combine two pickupsinput impedance 3.3 MOhmoutput impedance 3.6 kOhmadjustable gain up to 12 dB for each channelsupports 18V operation for 6 dB extra headroom power supply via 1 x 9V / 2 x 9V (18V) battery (not included)dimensions (L x W x H) 26.7 x 20.1 x 10.9 mm / 1.05" x 0.79" x 0.43"Warranty Information for Electronics: Electronic components such as preamps and circuit boards by Sadowsky, MEC, Seymour Duncan, and Bartolini are covered exclusively by the legal warranty period.

The NTMB+FL is well known to professionals for its very low noise and precise control. It is a 3-band tone control preamp with fully independent Bass, Mid and Treble controls. Often used in fretless instruments for more focused mid control, the FL voice is the same as the original Bartolini TMB from the 1980s.We re-packed the parts of the NTMB/918FL and NTMB3 2-part preamp system into a single module to make the NTMB+FL. The circuitry and parts are identical. Not only does the NTMB+FL take less space, but it also requires fewer wires, has even better noise rejection, and is easier to install. The NTMB+FL features a pre-wired adjustable gain trimmer which allows you to boost the input signal up to 12dB (4X) to match the output of several instruments or tune the output to drive your level-sensitive effects. Like all of our preamps, the NTMB+FL 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. We use professional double tin plated pure copper wire with durable semi-rigid insulation. This ensures the 5" pre-stripped wires dont flop around in the cavity and the wires dont cut through the insulation over time.

The TC series are our original preamps known as "The Chip". They are hand-made with discrete electronic components for very low noise, outstanding distortion characteristics when overdriven, and very long battery life. They are rugged, reliable and easy to install. In most cases do not require modifications to the instrument. The different versions provide different gain levels and area available as single or dual channel. The TC series are vintage designs that can be used in simple or complex ways. They include a boost signal that can be used by professional guitar technicians to further increase the output gain or to shape the frequency response for bass, mid, or treble boost. Because they rely on electrical current feedback for amplification, the tone is very well suited for high-output guitar setups. The TC series delivers very satisfying frequency-phase shift and asymmetric tube-like distortion when overdriven. Like all of our electronics modules, the TC preamps are internally shielded to reject electromagnetic noise and include internal filters to block AM and FM radio on the inputs. Bartolini set the standard of fully sealing the sensitive electronics. We use professional double tin plated pure copper wire with durable semi-rigid insulation. This ensures the 4" pre-stripped wires dont flop around in the cavity and the wires dont cut through the insulation over time. All TC preamps can be used in the un-boosted mode to provide equal amplification of all audio frequencies and very simple installation. The boosted modes allow tonal changes ranging from simple treble boost to a midrange spectrum shaping specifically designed to overdrive amplifiers to their best distortion sounds.single channel preamp for electric guitarsvery low noisegreat distortion characteristics when overdrivensuitable für high-output guitar setups18 dB (8x) Gaininput impedance 300 kOhmoutput impedance 3.6 kOhmpower supply via 1 x 9V battery (not included)dimensions (L x W x H) 26.7 x 20.1 x 10.9 mm / 1.05" x 0.79" x 0.43"Warranty Information for Electronics: Electronic components such as preamps and circuit boards by Sadowsky, MEC, Seymour Duncan, and Bartolini are covered exclusively by the legal warranty period.

TCT is the legendary original Bartolini on-board preamp. It has Bass, Mid, and Treble controls with very low noise and wide adjustment range. The TCT was briefly discontinued, but we brought it back due to high demand once it was known to be used by the brilliant Marcus Miller. It has vintage FMV (Fender/Marshall/Vox) frequency controls so each band affects the others and if all bands are set to minimum, the output is muted. This active tone control has the same tonal response as the early Fender amplifiers with Treble-Bass-Presence controls. The Bass and Treble controls give about 12dB boost or cut at 50Hz and 6KHz, respectively. The Mid control can cut up to 16dB at 300Hz, just like the original Fender Presence control. An MCT mid boost module can be added for boost of the mid for full 3-band control. They include a boost signal that can be used by professional guitar technicians to further increase the output gain or shape the frequency response. Because they rely on electrical current feedback for amplification, the tone is very well suited for high-output guitar setups. The TCT delivers very satisfying frequency-phase shift and asymmetric tube-like distortion when overdriven.

The four separate buffers in the TQB Quad Buffer can reduce electronic noise levels in instruments with passive pickups and some of our on-board preamps. Each buffer in the TQB is a low noise amplifier with a gain of 1, an input impedance of 270 kOhms and an output impedance of less than 10 kOhms. This low output impedance allows the TQB to drive 25 kOhm Volume or Blend controls very easily. This configuration was used in many instruments by Michael Tobias in the mid-late 80's. The tone quality was similar to that of the coils in parallel but with higher definition and lower noise. 4 channel buffer preamp for electric bassdiscontinued NOS equipment (not ROHS-compliant)used in some old Tobias era basses to buffer each individual coil of two humbuckersinput impedance 270 kOhmoutput impedance 10 kOhmgain factor 1supports 9V operation only, do not connect to 18V power supply via 1 x 9V battery (not included)Warranty Information for Electronics: Electronic components such as preamps and circuit boards by Sadowsky, MEC, Seymour Duncan, and Bartolini are covered exclusively by the legal warranty period.
