I'm pretty new so if this tread has been done recently, please don't chastise me too hard. Recently the salesman at the music store in my neighborhood told me I practically had to buy a new top of the line guitar cord, that the 15 dollar one I was using was not allowing the full potential of my guitar, (I play a Modulus). I wanted to ask everybody their opinions. Do the high dollar guitar cords, such as Monster, really make a difference in clarity and sound or is this just a bunch of sales pitch stuff??
