ART STUDIO V3 Microphone Preamplifier TUBE MP I'm not sure how to use it in detail, so I've only confirmed the sound output by switching each channel with an electric guitar and amplifier I had on hand. I haven't checked the microphone input because I don't have the equipment. I can't include the adapter, but I can provide a non-genuine one if you pay an additional fee. This is a used item. Please check the images for scratches, dirt, etc.
