How do I properly setup the Fretlight System with my computer and amp?

The Fretlight Learning System utilizes 132 LED's which naturally produce slight electronic noise that, if impropery connected with your computer and amp, could be heard through your guitar amp. Any proper musical setup should ensure proper grounding. The following list of DO's, DON'Ts and Cautions will help you ensure a good grounded signal and clean sound with your Fretlight Guitar:

DO's - When using a power cord with your computer, make sure the power supply has a grounded, 3-prong, plug. Most newer computers (2002 - Present) come standard with grounded power supplies. If you have a Laptop, you can certainly use it without connecting a power supply, thereby running it off its internal battery. Make sure that the Fretlight USB cable is plugged into a root USB hub on your computer. That is likely the USB ports on the BACK of a desktop - the front ones most likely NOT root USB hubs, merely duplicates. Make sure that you are plugging into a wall outlet that is grounded, in other words, has 3 prongs as shown above.

DON'Ts - Do not use a two-prong plug or a 3-to-2 adaptor plug. Do not use a two-pronged wall outlet. Only use 3-pronged, grounded, wall outlets. Do not use an external USB hub - the Fretlight must be connected directly to the root USB hub of your computer.

CAUTIONS - Try not to use power strips or extension cords as they WILL introduce extra noise into the system. For best results, connect your system as shown above. Make sure that you are using a shielded guitar cable. There is a difference when it comes to extraneous noise introduced into the system - use a good cable, we recommend using a name-brand cable.
