Musical Instruments

That guitar or drum set you bought years ago because you thought you were going to start a band can be turned into cash if your dreams of rock stardom never materialized. In fact, J. Money reported selling an electric guitar, amps and accessories on Craigslist for $225. You also can sell musical instruments online through sites such as Reverb, which charges a 3.5% fee on sales, or at a physical retailer such as Guitar Center.
