Preamp Bartolini Bass Adjustable Gain Buffer for magnetic AGDB 918 2 Original

100% Original authentic Bartolini

MADE IN USA

Dual channel buffer preamp for magnetic pickups.
The AGDB/918-2 provides 2 independent buffers in the same space as the AGB/918-2. This is great for separately boosting 2 pickups into either a simple dual-volume setup or even into an EQ preamp. When you have 2 passive pickups with low output, you can easily boost and isolate them with the AGDB/918-2 – effectively making them active pickups.

Like all of our preamps, the AGB and AGDB 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 don’t flop around in the cavity and the wires don’t 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 6dB extra headroom with no tonal change. Both versions delivery clear and transparent sound with extremely low distortion.
