The Baboomin Q-River 4-Strings Humbucker Headless Bass series is a highly cost-effective option. Featuring a classic combination of an alder body, hard maple neck, and rosewood fingerboard, it is equipped with Alnico 5 magnet pickups to ensure a classic bass tone. The headless design offers superior portability and lighter weight compared to traditional basses, while the optimized neck-body joint allows for effortless access to high frets up to the 22nd fret. 

This model also includes a comprehensive circuit adjustment system, offering controls for volume, balance, bass, mid, and treble frequencies, along with an active/passive toggle switch and mid-frequency selection.
