I'm a big fan of doubling rhythm guitar tracks... okay, strike that, I'm an addict! A fave is the old technique of combining a slightly dirty, crunchy track, with a more pristine, sparkling clean track, and I often use different chord voicings for each, to fatten things up a bit. Sometimes at mixdown, I find that I want one or the other of the two basic sounds to be dominant... ...and my question is this: what ways are available to achieve this, and still have a relatively equal (actual or 'perceived') balance between the left and right stereo images? Say for example that the 'dirty' track is desired to be dominant - can that track be compressed, while the 'clean' track retains the dynamics that were printed, such that the combined effect is that the timbre of the dirty track is 'heard' more distinctly, but perceived left and right balance is mostly equal? How about creative use of panning? I know that there is the approach of effectively achieving desired balance by combining tones onto one sandwich track - but my aim is to keep the stereo split somewhat intact. I'm mostly interested in approaches that apply to the use of two tracks, but I'm open to suggestions regarding use of additional tracks as well. Also, 'clean & dirty' is just one example; others, such as 'wet & dry', would also be applicable. This is probably old hat for some of you guys... Thanks in advance for any insight!
