For some time, I’ve been struggling with the tone of the QC with leads and mostly higher gain settings. The tone was very thin and low sustain. I have been tweaking the noise gate on the input block and noticed even when set to 0%, it still aggressively attacks the noise and cuts the guitar signal, making it sound very thin. I finally stopped using the input noise gate block, and started just using a simple gate on the first block, and it has made a huge improvement to the tone and sustain. I think there may be a problem with how the noise gate on the input block functions that NDSP might want to look at.
