Is your guitar amplified (battery) or line level? Amplified guitars probably would give signal overload. Your guitar uses magnets, so it may be that you are just too close to your computer or the Ozone. There are two 1/4" inputs on the Ozone, the one for instrument should be used. Why do you plug into the Ozone? You can use a 1/4" to 1/8" adaptor directly to your computer. xxxxxxxxxxxxxx I have been trying unsuccessfully to record guitar into Garage Band via an M-Audio Ozone keyboard. When I create a new Real Instrument guitar track, I get a loud feedback noise. This noise occurs whether or not the guitar is plugged into the Ozone. Anyone have any experience with this?
