The VOX Pathfinder 10 is a guitar amplifier for home practice. It's lightweight but can cover a relatively large volume. This is a used item, but there are no functional issues. There was no crackling when turning the knobs. The exterior has minor scratches, so it is being sold at a slightly reduced price. - Brand: VOX - Controls: GAIN, TREBLE, BASS, REVERB, VOLUME - Power: AC power - Input Terminals: INPUT terminal - Model: Pathfinder 10 Thank you for viewing.
