This is a Markbass Little Mark Ⅲ. It is a junk item due to the following defects: It takes a while to start up after turning on the power. This seems to be a common issue with the Little Mark Ⅲ, and it has been in this state since I purchased it used. Sound is produced, but it is not a normal sound (a thin sound is produced). In particular, the Gain knob is not working properly. The other knobs seem to be working. I do not know the cause or location of the defects, so please be aware of this. The amplifier head unit and power cable will be shipped. Please consider purchasing this item on the assumption that you will repair it, such as if you are able to repair it yourself.
