Guitar Magnetic and Piezo Buffer – MPB1
Dual channel buffer preamp for guitar with acoustic tone shaping piezo channel and adjustable gain magnetic pickup channel.
how to buy
The MPB1-918 provides 2 independent buffers for use in instruments with magnetic and piezo pickups. It features adjustable gain for the magnetic channel which allows you to boost the input signal up to 12dB (4X) while maintaining flat frequency response. The piezo channel has built-in tone shaping to provide an acoustic-like voice to an electric guitar with piezo bridge. It is less than ½ the size of a 9-volt battery making it ideal for instruments with limited cavity space. The MPB1-918 provides a strong output signal and isolation from external equipment that may otherwise adversely affect pickup tone.
The kit includes a blend pot for mixing the magnetic and piezo signals into a common output for connection to an EQ preamp or direct to the jack. The MPB1-918 is ideal for providing excellent tone from an instrument with 2 magnetic pickups and a piezo bridge pickup. Both channels deliver clear sound with extremely low distortion.
Like all of our preamps, the MPB1-918 is internally shielded to reject electromagnetic noise and includes 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 don’t flop around in the cavity and the wires don’t cut through the insulation over time.It 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.
