Ok, well I own a Behringer board which runs into an SBLive sound card. I play samples back in winamp to see what the spectrum analyzer in winamp shows. On my drums tracks they are able to span the entire length of frequencies, which is what is supposed to happen. The problem is when I record guitar that the guitar sounds week and when I look at the spectrum analyzer it shows that it is only showing up in the lower part of the spectrum. A friend of mine who does a lot of recording suggested at first that I might want to get a graphic equalizer to bring up the higher ends, but I fear this may bring up something which is not there. This will create noise. Another idea was that it could be the pickups in my stratocaster guitar? Or is it that I have a crappy sound card? Please help!
