The Phil Jones Bass Nanobass X4C Combo Amp is a compact, high-fidelity bass amplifier designed for players who demand clarity and precision in a small footprint. Its four 4-inch extended-range speakers work together to produce tight, controlled lows and exceptional note articulation without the boom or muddiness common in small combos.

Engineered for detailed response, the X4C captures the full character of your instrument—from deep fundamentals to harmonic overtones—making it an ideal solution for home practice, studio sessions, and low-volume live environments. Its focused projection ensures every note remains clear and balanced in the mix.

Portable, efficient, and built with Phil Jones Bass’s signature attention to tonal accuracy, the X4C is perfect for bassists seeking professional-grade sound in an ultra-compact package. Whether used as a personal monitor, desktop amp, or rehearsal companion, it delivers refined bass tone with impressive clarity.

The X4C includes a USB Type-C port for Power Delivery from a 20-Volt Laptop power bank. The higher the capacity in mAH, the longer the amplifier will be able to work. 20,000MAH will be a good start.
