Guitar cable is coaxel ,Meaning it has a inner core and is wraped in sheilding
witch is your ground. GUITAR CABLE SHOULD NEVER !! BE USED AS
SPEAKER CABLE. Speaker cable is just two strands of wire like your
home sterio or monster cable. you should be able to unscrew the barrel
and distingush the 2 ?
because guitar cables are designed to handle a few volts at most, not several hundred watts of power.
Plus you know how your tone loses high end when you run it thru long cables? well thats because the cable is acting as a giant capacitor.... do you really wanna blow 100+ watts into a big capacitor? on a tube amp?
Now I find this out......I forgot my speaker cable one night for my extention cab and used one of my guitar cables. For the next few weeks I noticed that my tone was off but I couldn't trace it to anything in particular(didn't check the cable itself). Last week I was playing into my RP300 and it just went dead all of a sudden. I tried everything and finally figured that it was the cable. I plugged into my amp with a spare cable and low and behold the tone was great again.
U can blow your amp with a guitar cable running into your amp especially if its a tube amp. I just used the wrong cable and got told to use a speaker cable. USE a speaker cable cause a normal cable will get so hot becuause its insulated and it will everntually burn out.
