I have been kinda having this problem recording bass where I can get a great "heavy" tone for the lower notes, but then when the bassist goes up high to do some little fill, the higher notes are quieter and totally get lost in the mix compared to the booming powerful low notes. I have tried compression and stuff, but it doesn't help a lot. The only way I have found is to eq the bass so that the low notes aren't as bassy, so therefore they are the same volume as the higher notes, but that kinda kills the point of having the bass sound like I want it. Is this just one of those things where you have to pick either a big low sound where you can't hear the high notes or a more mid-rangy sound with less bass but a more visible high end?? Help?? I have been using the sans amp bass driver. FYI.
