- The first time the backboard was cut, we made it too small, so it had to be cut again.
- The red wire of the piezo element was accidentally cut off while trying to secure it, so another piezo element had to be bought.
- It was difficult trying to loop the guitar string through the PVC pipe and into the machine tuner.
- Looking back on it, putting frets on the neck of the guitar would have been useful for better playing. Also, notches could have been put on the guitar for a neck strap for easier handling.
In the end, however, everything went pretty smoothly.
