I have about 4 Shrednecks and I take them every where! I use them on the phone or even now surfing the web. I drive with them on long trips and my callous are massive as well as finger strength when I get home. 3 hrs and your fingers are Hercules! I practice bends and scales. Picking when I don’t drive. Fits in a shoulder bag and can be played even on a airplane with no one knowing. 16 inches long-pack it every, any where The dreadneck from guitar center is more for guys that have played for some time and do not need to hear the actual note. It’s a practice tool and exercise device that feels like a guitar neck. I make up exercises for my self on weak fingers. I love the “Dreadneck”.
