Nanotechnology breaks the sound barrier with the X4 Nanobass, which is the most compact and portable combo amplifier ever designed by Phil Jones Bass for desktop and practice applications. It is a highly efficient mini engineering marvel that redefines transportability and "Tone To Go". It is a 35 Watt amplifier with a 4" speaker and 3 Band EQ that not only rocks with bass; it will also provide the dazzling tone for other instruments including guitar, ukulele, violin, and electronic drums.

The practical and versatile design includes an auxiliary input compatible with iPads, iPods, and drum machines, and is Bluetooth-equipped for music listening enjoyment and other applications. PJB's proprietary NeoPower 4-inch speaker delivers a full frequency range that achieves ultimate tonal clarity and transparency for instruments as well as high-fidelity sound to any source fed into the auxiliary and Bluetooth inputs.

The X4 weighs just over 5 lbs and is small enough to fit in a backpack. It is available in Black, Red, and White colors. As with all products in the PJB family, it is constructed from the highest quality materials and built to provide years of enjoyment and "Tone To Go" anywhere in the world with its built-in worldwide AC voltage input.
