Compact and portable PG-10 guitar/bass amplifier. - Model Name: PG-10 - Function: Guitar/Bass Amplifier - Controls: Volume, Bass, Treble, Headphone Jack - Brand: Photogenic Thank you for viewing. I received this a few years ago but haven't used it, so I'm putting it up for sale. I've confirmed that it powers on, but I haven't been able to fully test its functionality as I don't have an instrument to connect it to. Therefore, I'm selling it as junk.
