yeah,I do. My first was acheap $100 guitar that had all of the strings out of pitch and they would always pop. I go to my friends house and play stairway to heaven.(lol)He plays some double-neck one.He has one with the zack wylde mesmerize on it.
i know which letters the notes are (well, the instructions on how to get started told me XD). Just not what they should sound like. I used the electric tuner to listen to the laptop - it picked the right notes. when it listens to my guitar (which sounds the same as the laptop to me) it says i'm way off.
