Chord Epic instrument speaker cable (head to cabinet) It happens so often – a beautiful hand built valve amplifier and speaker cabinet, connected with a cheap guitar cable! Using a guitar cable in place of speaker cable won’t just strangle the sound, it could actually short out and cause damage to the amplifier. Instead, try using our Chord Epic speaker cable fitted with quarter inch jack plugs (XLR and Neutrik Speakon connectors are also available) between your amplifier and speaker cabinet. It features heavy gauge silver-plated, PTFE insulated conductors inside a PVC jacket that in turn is protected by a dual layer foil and braid shield with translucent outer jacket. The standard length is 1m jack to jack. Other terminations and lengths are available to order.
