Actually, the cheaper Monster Cable that I have is ever so slightly smaller in diameter than a standard one from my local guitar store (Shilo Music). And the tip has a slightly different shape. The MC cable worked fine in my Rogue, Rick, G&L, and Fender guitars and basses. It was my '89 Elan that did not like it. So, I'm now using a Horizon brand - they are about 10 bucks for a 10 ft'er. No noise and a lifetime warranty though my guitar store.
George at Shilo wsa telling me about a killer cable made by PRS that has a tangle free cable for about $40. He was out of stock when I got the Horizon cord.
