This is a Fender Studio 15 guitar amplifier. Dimensions are 300mm (height) x 330mm (width) x 180mm (depth), excluding the handle and cord. It works without any problems. It's an old unit, so please understand there might be some crackling in the potentiometers. It delivers beautiful Fender-style clean tones, and when you increase the gain, it can also produce high-gain sounds. I think it's a perfect small amplifier for a bedroom. For improvement, please practice with a real amplifier instead of an amp simulator.
