Okay, I'm confused. sm7 pedal?
You mean sm57 mic? (microphone)
So that clip was recorded with an sm 57 mic on your bass amp?
It does sound better all ready but still bad with that soundcard.
Practice to a metronome often, then when your playing is tight (perfectly in time with the beat or metronome) quad track the riff (record 4 seperate tracks of the same exact riff) and it will sound even better still. This is common practice. The idea being that you want to play back the 4 tracks layered together on top of each other and pan 2 hard left and 2 hard right (2 guitars in the left speaker, 2 guitars in the right speaker) and have it sound like its actually 1 gtr in left and 1 in right. This process makes the gtrs sound bigger and better and more metal.

If they are not tight, you will hear it as it will sound like 4 gtrs played sloppy and we don't want that.
Also play around with that distortion pedal. Might as well work on finding an okay tone with what you have. It doesn't sound like it's used in that clip.
Well, you got the sm57 (I think) and that is a start and a step in the right direction.
Pedal?
