Their website says 1-year warranty, and these are well past that. Purchase receipt also required, which I no longer have either.
Edit: I misspoke-- I misread the website. Cables do come with a lifetime warranty except for one type (an 8 pin type, not an instrument cable). However the warranty is only against manufacturing defects, and I would guess that wear and tear would not qualify. And again, I don’t have the receipt so I’m out of luck there. Hell, I don’t even remember where I bought them, was probably online somewhere…
The text printed on the cable sheath says Monster Prolink - Monster Classic. The jack has a red stripe. Checking the Monster website, these are their least expensive model, listing at US$17.95, so my recollection of around $20 seems right. Same as above though, no receipt, so I don’t think I have any recourse for return/replace.
So… is this a case of get what you pay for? Will their $40 cables last twice as long as the sub $20 units, etc?
