Bartolini AGDB-918 Dual Adjustable Gain Buffer

Description

The Bartolini AGDB-918 is a compact dual buffer built to condition your signal before it ever hits your onboard preamp. Rather than just boosting output, it gives you two independent gain controls so each pickup channel can be dialed in separately — handy for balancing dual-coil setups, blending pickups with different outputs, or fine-tuning any circuit where one channel runs hotter than the other.

Because it’s a true buffer stage, the AGDB-918 keeps your low end tight and your top end intact, delivering a notably flat frequency response with a low noise floor. That means less hiss, less signal loss through cable runs, and a cleaner foundation for whatever preamp or EQ stage comes after it.

Flexibility is built in: it runs happily on either 9V or 18V power, so it drops into most existing Bartolini or third-party preamp wiring without forcing you to rethink your battery setup. It’s a small addition with an outsized effect on clarity and headroom.

• Dual adjustable gain channels for independent control
• Works with 9V or 18V power supplies
• Flat output response with low noise floor
• Compact dimensions: 33mm x 26mm x 13mm

Ideal for bass players and builders looking to tighten up an existing preamp circuit or add precise gain-staging to a custom electronics build.
