The Phil Jones Nanobass X4 is an excellent combo amp that combines sound quality and portability. I am selling it to organize my equipment. I have only used it at home. In my subjective opinion, it is in beautiful condition. Only the main unit and power cord are included; the original box and instruction manual are not. The Phil Jones Nanobass X4 is a very compact and lightweight digital combo amp, particularly known for its portability and sound quality. This amp has a 35-watt output and is equipped with 4-inch speakers, designed to accommodate a wide range of instruments. Key Features: - Size and Weight: Approximately 6.3 x 7.9 x 7.8 inches (about 16 x 20 x 20 cm) and weighs 5.3 pounds (about 2.4 kg), making it very lightweight. - Sound Quality: The frequency response is from 68Hz to 15kHz, with particularly strong bass reproduction, providing a clean and clear sound quality. It is equipped with a 3-band EQ (bass, mid, treble) for fine-tuning the tone. - Connectivity: Features Bluetooth 5.0, allowing music streaming from smartphones and other devices. It also has a 3.5mm stereo Aux input, enabling connection to drum machines and other instruments. - Design: Stylish appearance, with a popular white color. The internal structure is solid, designed to suppress cabinet resonance. This amp is compatible with various instruments, including acoustic guitars, electric guitars, and even keyboards. In particular, it excels at naturally reproducing the tone of acoustic guitars, making it suitable for rehearsals and small live performances. However, it does not support battery operation and requires AC power.
