It’s a fantastic choice for players seeking a transparent boost and precise EQ control, especially those in funk, jazz, or modern rock bands where clarity is paramount.

Frequently Asked Questions
Switching to passive mode removes the preamp's gain and EQ, providing a more traditional, less colored bass tone – great for blending in or dialing back the active boost.
The 18V provides a noticeable increase in headroom, preventing clipping at higher volumes and giving you more dynamic range, but it’s not essential for quieter playing situations.
Bartolini offers a slightly different tonal signature – less aggressive and more focused on transparency compared to the often more saturated sounds of Aguilar or EBS, but still delivers excellent control.
