In case your IEM headphones are buggy (any other recorded music sounds distorted as well) you know how to solve the problem.
Besides that you know that internal clipping is possible for some blocks? I had it because I have a send-return combination in my presets and I did internally overdrive these blocks with turned up too loud amp blocks (amp blocks too loud, but very low volume setting at the very last block in the grid so getting no clipping LED). It did only clipp internally when I was strumming very loud, so with a cranked up monitor I usually didn't do this, but with the IEM it did not hurt to do so. You see the point.
After turning down the volume in the amp block and turning the volume up again in the very last block that internal clipping went away. Absolutely clear sound.
