Yup, radio shack is good for the basic stuff. You might at some point want to get familiar with a real electronics shop in your town. The dirty one that smells like cigars. The more you get into recording and music in general, the more trips you'll be making for various parts. The better stores will sell the higher end stuff and the staff will be knowledgable...in other words, you CAN ask them questions without receiving the RADIO SHACK DUMB-FOUNDED STARE OF DEATH.
