Please read the following description and profile. VOX amPlug2 Bass AP2-BS Bass headphone amplifier, junk item As stated, this is a junk item. Hum noise is audible. From volume levels 1 to about 5, I can't hear the bass sound, only noise. When increasing from 5, the bass sound faintly becomes audible, but even at 10, the sound is quiet, and the noise is louder. The bass sound changes when the tone is adjusted, but the hum noise changes even more, and when the tone is set to 10, the noise can be so loud that it feels like it might damage your eardrums. The rhythm patterns play correctly, and the volume is also fine. I have never used the AUX terminal, so its operation is unconfirmed. Therefore, this is being sold as a junk item. Please purchase this for display purposes or with the assumption that it will need repair. Shipped via Rakuraku Mercari.
