Adopts a short scale string length of 30.3 inches (770 mm).
It also has an output jack, so it can be used as a regular base.
Uses the same open back structure as a guitar amplifier.
Punching hole back plate creates natural and pleasant sound.
Equipped with an output jack, it can also be connected to an external amplifier.
The built-in amplifier has a volume adjustment trimmer, which can be adjusted from the back of the body.
Volume adjustment trimmers are calibrated correctly during shipment. If you turn the trimmer to the right full, it may cause oscillation and cannot play, but this is not a malfunction. After oscillation, turn the trimmer to the left and lower the amplifier volume.
The trimmer also changes loud with a little adjustment. Please note that slight adjustments are required.
