Speaker Cable or Guitar Cable

[indysmith]

Just a quick one...
What's the difference and how do you tell? apparently yu shouldn't use them to do each other's jobs... why is this - is it dangerous to the equipment or just the tone? - if a signal only flows one way through a cable does that mean that it's a speaker cable?

[HTH AMPS]

guitar leads have one 'core' plus a 'shield' (hence it being called shielded single-core cable).  The shield wraps around the core and is grounded so any noise interference is (hopefully) passed to ground.

speaker cable is twin core and has no shielding - it will sound noisy if used as a guitar lead.

does that help?

You can damage your amp (especially the transformers if you use a guitar lead for speaker cable).  Also try and afford the best cables you can...they really do make a tonal difference.

plus speaker cable can handle higher load so if you use a attenuator box of any kind or play with or your amp wound up & use instrument cable you will burn something out either your cable if your lucky or your amps transformer if your not.
