Guitar Cable

I would highly recommend the circuit breaker cables.  Whilst they are of course a little more expensive they completely eliminate the popping noise you associate with plugging your guitar in when the amp is turned on and the volume is on.  This could save your valves in your amp, speaker cone but on a basic level its lovely and quiet when you plug in.

Planet Waves cables are highly recognised as top quality cables and endorsed even by one of my great inspirations Joe Satriani - If they are good enough for him, they are good enough for me - and hopefully you too...
