PowerWire (patent-pending) is a 20-foot cable with an embedded amplifier and batteries to bring you a crystal clear response from bass to high-end – the first of it’s kind in the music industry!! PowerWire makes passive, ordinary cables of the same length sound muddy in comparison – a phenomena known as phase distortion, which is eliminated by the use of an active drive on the cable. PowerWire provides a clean drive of the cable length, eliminating the interaction between passive guitar coils and parasitics in the cable, providing you with more of your original playing sound. Custom effect versions are also available. Get your PowerWire from R&M Tone Technology today!!
