This little Bartolini is a lifesaver for acoustic bass players or anyone using piezo pickups – it cleans up the often harsh sound and adds a bit of juice without muddying things up. It’s incredibly transparent, so you’re getting a more natural representation of your instrument. Ideal for studio work or anyone wanting a subtle boost and improved clarity.

Frequently Asked Questions

Yes, the high input impedance makes it perfect for Fishman's high-output piezo systems, smoothing out the high frequencies and improving overall tone.
While it accepts a single 9V, using two in series (18V) unlocks the extra headroom and a slightly more powerful signal – highly recommended for best results.
The Bartolini offers similar transparency at a more budget-friendly price point, but the Radial provides more comprehensive features like EQ and a DI output, making it a more versatile, albeit premium-priced, solution.
