hey guys. I just bought the RP350 guitar sound processor. It has a function called learn a lick, which records 10 second clips of songs and can play them back up to 25% of it's original speed. to use this i would need a cord that is similar to a guitar to amp one, only it needs to be the size of an Ipod. does anyone know where i can find a cord like this? (1/8 size if it helps, it's all the manual said about cord size.)
