I’m noticing a consistent light crackle a second or so after playing a chord or single note. Thought it was a bad cable. changed them all .. Same. Used different FRFR speaker. Same. Changed guitar. Same. Rebooted the XL and it stopped for a while. Now it’s back at any volume. Also I am aware there is a distinct lack of bottom end or warmth with any preset, compared to other modellers I have. And finally I am not getting any natural sustain. Playing feels awkward. Like a gate kicking in..Not super impressed so far. Hope this is a firmware issue or it’s going back to the reseller. I’m on the latest version
