Anyone know why when I am recording my bass on my computer the sound is kind of muffled but when I play it back it sounds great?
What soundcard do you have? Older soundblasters are not really full-duplex. They can record and playback at the same time, but at the expense of sample frequency, if I remember correctly. That may be the reason for it. Lower sampling frequency, less high. Only when you either only record or playback, you can use the full sampling rate, with gives you back the highs. That would be my guess, but I could be wrong. Perhaps you can give more info on your pc hardware.
I'm using an Aardvark Direct Pro 24/96. It is made for recording. I will look into the settings and what I can find. Thanks.
The Aarkvark is a pro level card. It should have no such problems. Check your settings, both for the card and your recording software.
