[LAU] Balancing volume between smooth and popping bass

All, I'm looking for a way to balance the sound between regular playing and pop/push type of playing on a accoustic bass guitar. The guitar is both miked (M-Audio pulsar) and has a balanced line-in for the embedded pick-up (of not very good quality as it lacks picking up the high notes). That's two stereo tracks in Ardour as I feed both mono signal in the right and left of each track. Maybe I shouldn't do that. In any case, the push/pop notes are blasting when compared to regular playing. A bit of blasting is OK, but there's too much contrast now. Is there a receipe in recording techniques that addresses that kind of configuration and enables control over the loudness difference from a sinle intrument in a single take ? Any ideas/suggestions appreciated, Cheers.
