Google says that's a guitar amp, as do all the online stores that sell it. All bass amplifiers I've ever seen are noted as "bass amplifiers", so I don't see any confusion here.
It claims to be a 10 watt practice amp and has a slotted back cabinet. This isn't a design that will produce much bass, and certainly won't provide much volume, but maybe it's adequate for the bedroom. Cord storage is just a "benefit" of having an open slot: it's not a "feature".
The Bass, Middle, and Treble knobs are tone controls, often referred to as EQ, short for equalization. This is stated on the various web pages where it is being sold.
The Gain knob is used to how hot a signal is through the preamplifier, and high gain settings are often used to get an overdriven sound. The Boost button probably adds even more gain for more distortion. The Volume knob sets the overall output level. There is no reverb (an effect) on this little box.
But if you're playing bass you really need an amplifier made for bass. Sure, you may be getting some sound out of what you've got, but you won't appreciate it until you get proper kit.
