A bass guitar combo with a power of 20 W, ideal for home practice. The combo has one instrument input. The "gain" control adjusts the level of the input signal in the preamplifier, so you can achieve a slightly distorted sound. When the compressor is on, it controls the compression rate. Other controls include master volume and a 3-band equalizer to set your preferred sound. The AUX input is used to play music from an external device, e.g. MP3, smartphone. Thanks to the headphone output, silent exercise is possible.
