Hello, I just started playing guitar a couple months ago, and I am thinking of investing in a wah pedal. When you buy a pedal, does it come with an extra cord to hook it up to the amp, or would I need to buy a new one? I just have the guitar, the cord that hooks the guitar to the amp, and the amp. I would buy the wah off of eBay, so it probably wouldn't come with any cords that weren't part of the original package. I would hate to get the pedal, and then have to wait until I have time drive an hour to Guitar Center just to buy a cord that may not be necessary. Thanks in advance for your help!
