All right. Here's the issue... I'm getting a really weird high pitch interference will all my bass signals. It reminds me of what happens when someone notches up the higher freqencies in a mix. I'm using Adobe Audition (Which I've used plenty times before) with Windows Vista What I've done Direct in the the line in Direct into the mic Used to different Preamps (one usb, and one direct out) It's there with my headphones on and/or off Now...obviously, the quality changed with all of those, but nothing changed with that high pitch sound. If desired I could record something real quick and send it so you can hear it for yourself. I originally thought it was because I was going direct and perhaps it was my pickups...so then I turned to mic'ing the bass cab...same problem. I'm getting great signal...but...still there. My guitar is not doing the same thing, and neither is my programmed drums on play back So I am pretty sure it's in the recording process and not on playback. However, I have not listened to any recordings of this on any other computer. Any help would be great.
