The Monster Cable Standard 100 is an instrument cable that is designed for uses of all types. I've used these cables for a variety of different applications, but primarily in the studio and on the stage for use with electric guitar. I've also used them in the studio for keyboards and bass guitar. These are great all purpose cables and they come in a variety of different lengths if I'm not mistaken. The ones that we've got in the studio where I work are about 15 feet or so for the most part, but we do have a number of them on hand. These cables are built extremely well and are definitely some that will last a long time, especially in a studio environment where they won't see any hard gigging damage done. Monster has built up a reputation as being one of the best, if not the best when it comes to making cables of all shapes and sizes. I've always liked their work and definitely feel secure in my connections when I'm using these Standard 100 Instrument Cables. The one in the picture above has the right angle on one end, but I'm pretty sure that there are some in this series that have both ends straight, although we do have both styles on hand and I may be confusing them with another type. While these might not be as cheap as some other instrument cables out there, the Monster Cable Standard 100 Instrument Cables are worth the extra dough in my opinion since they'll undoubtedly last a while and really aren't that much more. I'll usually use either these Monster cables or Planet Waves, as I believe that these are the sturdiest instrument cables that we have at the studio where I work. These are definitely worth knowing about if you're looking for some instrument cables for any sort of use.
