OK, now what you need to do is get close to the sound you want, but don't worry so much about the final sound until you are in the total mix (guitars, drums, synthesizers) as it may not matter in the "total mix". You could possibly improve that by using some EQ. But wait until you have more of the total mix recorded and defined. That is why as a general rule you don't EQ to a solo/single sound as it is more important how it fits the mix verses just how it sounds.
Go ahead, do some recording, get a mix, then put it up in the MP3 clinic and work from there. Main point is, you have removed a negative sound from the source verse trying to remove it afterwards. It is easier to EQ than to remove noises.
