This is the digi-zo ultimat, the top-of-the-line model in the ZO-3 series of built-in amplifier guitars. It uses a medium scale similar to a Les Paul, and is equipped with the ULTIMA circuit jointly developed with Digitech. It also has a built-in multi-effector, rhythm box, and tuner, so you can enjoy everything from practice to street performances with just this one guitar. The control panel uses easy-to-operate touch panel switches, and the speaker is made by FOSTEX. There is a paint chip on the lower back of the body, but otherwise, I think it's in relatively good condition for its age, including the body, neck, and metal parts. I checked the condition by turning on the power. I think there are no problems with the display and operation of the touch panel, and the operation of presets and effects. Currently, there is only a little white noise, and there were no problems with playing. I was able to use it without any problems when connected to a different amplifier. However, please understand that it is quite old.
