Is anyone getting a lot of background hiss (like a high gain amp on 12)with the new crunchstation presets. other presets are pristine.
Distortion by nature will bring up your noise floor, most of the CrushStation presets are pretty high gain. Are you using the Gate in the CrushStation presets? If your guitar or signal path is unusually noisy, it might be above the gate threshold.
Conversely, if your guitar signal is quiet, it might sit closer to the noise floor, and getting a distortion sound you like boosts the noise floor too much. For this, I would recommend increasing the Input Gain on the H9.
