Description
The Bartolini AGMPB/918 solves a common wiring headache for players running both piezo (or other microphonic transducers) and magnetic pickups in the same instrument. It offers a dedicated high-impedance input for the piezo side, plus full channel isolation for your magnetic pickup, so each signal stays clean and unaffected by the other.
- Dual-channel design: high-Z input for piezo/microphonic pickups, isolated channel for magnetic pickups
- Trimmer pots on both channels for true, independent gain adjustment
- Boosts output up to 12dB (4x) while keeping response perfectly flat
- Compact footprint – less than half the size of a standard 9-volt battery
- Ideal for instruments with tight control cavities
Beyond just boosting signal, the AGMPB/918 acts as a buffer that shields your pickups from the loading effects of cables and downstream gear, preserving tone integrity from instrument to amp. If you’re upgrading from the older MPB2-918, this unit is a direct improvement: wiring is simpler, and you gain real, adjustable control over both channels instead of a fixed setup.
Whether you’re building a new instrument or retrofitting an existing one that mixes pickup types, this little preamp delivers a stronger, more consistent output without sacrificing space or tonal accuracy.
