I noticed a particularly annoying issue with my UR28M. Plugging in a guitar with a reasonably hot (passive) treble pick-up results in the clipping of the signal when playing hard. Preamp gain and the PAD button do not have any effect on this, when the signal is low, the clipping is still there, only quieter. The waveform transients appear to be completely cut off regardless of the preamp level. The clipping problem does not occur when the Hi-Z button is not pressed in, so it looks like a problem with the DI section.
Anyone else have the same problem?
