When building patches, I'm running into noise/clipping quite often with some combinations of settings. It seems to occur with my single coil guitars. My input level into the Axe is right (tickling the reds or below), and I'm using stock presets with moderate MV and Drive settings. Turning Grid Modeling off doesn't seem to affect it. Speaker drive is 0. My Instr In level on the Axe is at 49.8%.
In the attached clip, I first play my Fender American Strat in the bridge position with a patch copied from 006 - Top Boost, with all other blocks except Amp and Cab removed for simplicity. You'll hear the distortion there, especially when digging into the notes (no red appears on the Axe input LEDs when playing). It's not a Townsend arm spin - just digging in to a hard level in the range you would typically play in. In the second part of the clip, I have turned off the Bright switch and the problem is much lessened. In the last part of the clip, I recorded the bypassed guitar signal for reference to show the distortion wasn't coming from there.
I was wondering if this is expected behavior from these amp models and I need to kill treble-related parameters to tame this or if there's something else at play. It doesn't seem right as the noise is so prevalent on stock patches (I could see if they were my patches I may have spun something the wrong way, but the stock patches shouldn't sound this way right?). The Drive (5) and Master (7.8 ) for the AC30 in this example seem fairly moderate. People recommend putting the AC30 master cranked or near, but that only increases the noise in this case. The attached clip is one example, but I find it occurring in many other amps and stock patches as well.
