If your room is noisy, try close mic'ing the guitar. Try it in both cardioid and omni. Start at the 12th fret and move up and down the neck. As you move toward the sound hole, the bass outbut will increase big time, as you move away from it, yhe sound will get thin. Find the right spot in between, which is usually the 11th to 14th fret. When I say close, I mean 4" from the guitar. As funds become available, upgrade the preamp. Yeah, the Blue Tube really may not be better than the pre's in your Soundcraft, which just shows you need a preamp. Consider FMR Audio RNP or better, (in my opinion) Grace Design 101. Whether you use bass cut or not depends on the song and mic placement. As the mic moves away from the sound hole, you'll need bass cut less and less. Frankly, I prefer not to use bass cut when possible, but sometimes you have to. If little speakers are overloaded by the low notes, you know you need bass cut, or you need to move the mic to a lower fret. Enjoy your mic. I don't use the C-3 for guitar myself, but it wouldn't be the last mic on my list, either.-Richie
