Bartolini Adjustable Gain Magnetic/Piezo Buffer (AGMPB Kit), Dual Channel
The AGMPB/918 is a dual-channel buffer/preamp that provides a high impedance input for use with piezo or microphonic transducers and channel isolation for magnetic pickups. Both channels are equipped with trimmers for adjustable gain allowing you to boost the output signal up to 12dB (4x) while maintaining a perfectly flat response. It is less than 1/2 the size of a 9-volt battery making it ideal for instruments with limited cavity space. The AGMPB/918 provides a powerful output signal and isolation from external equipment that may otherwise adversely affect pickup tone. This is an upgrade replacement for the MPB2-918 simplifying wiring and adding true gain adjustment to both channels.The AGMPBoo is a further advancement that adds connector pins for up to 7 industry standard piezo bridge saddle plugs. This simplifies wiring connections further and eliminates the need for a separate 2.0mm pitch summing connector. The AGMPB/918 is ideal for providing excellent tone from an instrument with 1 or 2 magnetic pickups and a piezo bridge pickup. Both channels deliver clear and transparent sound with extremely low distortion. Like all of our preamps, it is internally shielded to reject electromagnetic noise and includes filters to block AM and FM radio signals on the inputs. Bartolini set the standard for fully sealing the sensitive electronics. We use only professional double tin-plated pure copper wire with durable semi-rigid insulation. This ensures that the 4-inch pre-stripped wires do not flop around in the cavity and that the wire does not cut through the insulation over time. The buffer/preamp can be used with a single 9-volt battery (9-volt operation) or with two 9-volt batteries wired in series (18-volt operation) for 6dB extra headroom with no tonal change. It delivers clear and transparent sound with extremely low distortion. The buffer is sold as a kit including a 25KOhm blend pot.
