This unit is the "Micromark," a big hit model, featuring a 6-inch speaker, a lightweight and compact body, powerful 50W output, and excellent handling due to its ultra-small size, allowing you to easily carry the Markbass sound. This is an early model imported by Arai Trading. The difference from current models is that this one was made in Italy, so it has a sturdy iron handle. The headphone jack is on the top control plate. When I bought it new, I thought it was very well-made, but the manufacturer's suggested retail price was nearly 90,000 yen, even though the yen was strong at the time, so maybe that's why. By the way, it seems that production is now in Indonesia. The condition is what you'd expect from a typical used item. There's no noticeable crackling, and the headphone and AUX jacks are functional. Incidentally, the headphone jack outputs sound from both the headphones and the speaker unless you turn off the speaker with the switch on the back. I think this is a feature for recording, despite its small size. The sound is definitely Markbass, despite having only two knobs. Personally, I feel it has more depth than the current models, but that's just my personal impression. The volume control is really exquisite and very easy to use for home practice. Plus, it can produce enough volume for a cafe live with a three-piece band, if you don't mind the genre. In the photos, the carpeted surface looks whitish, but in reality, it's solid black and not dirty. Accessories include only the power cord. The original cord was broken, so I'm including a Classic Pro cord. It doesn't affect the sound, and it's easier to use because it has a standard outlet shape. Also, the cord is thin, so it's easy to move around. SPEAKER: 1x6" Output: 50W RMS (AES Standard) Weight: 4.2 kg Dimensions: (H)22.5 x (W)22.5 x (D)21.9 cm
