The Vox VGH AC30 is a headphone guitar amp that enables you to jam away at home, in the studio, or outdoors just by plugging in your guitar. They allow you to practice when all needs to stay quiet around you. When the power is turned off, they can also be used as a standard pair of headphones. They feature reverb, chorus, and delay effects to dial in the perfect sound. These headphones are also extremely comfortable and can comfortably be worn for long periods.
