The VOX AP-MT wireless system is metallic and durable, perfect for guitar playing. - Brand: VOX - Model: AP-MT - Type: Wireless System Thank you for viewing. I was using this until recently. It's convenient for practicing guitar and bass while easily listening to metal-style distortion through headphones. Since it's an older item, there may be some crackling (it could also be a problem with the guitar itself). No returns or exchanges. Please also understand that it will be sent with simple packaging.
