I have 2x HX Stomps. 1 has never given me any issues. The other has had this drop out issue. It got sent back about a year or so ago and they did something to it. The screws were tampered with. It came back with newer firmware than was available at the time and didnt have any issues until recently when it started doing this again. Both of them have always used the L6 power supply as I had room under the board to tie it down. Its started doing this again but Ive always just plugged in a master power supply cable and everything powers up from that. Ill try letting the rest of the board start up before turning on the L6 and see if that helps.
