Surprised to hear you and
@gillento had this experience. I'm not Origin fanboi, so it's not that, I've just found the DCX to be a super versatile little beast, so the fact you haven't been able to find a workable sound after a week is the part I find unexpected! I run a rounds-strung Rickenbacker into a Mesa D-350, so it's not lightyears away from your Stingray > D800+ setup. Well, before I say that, how do you run the onboard preamp on your bass? Also, are you running cabs (or monitors/floor wedges) on stage, or going IEM?
I see your signal chain; (nice choices, btw!) I assume those aren't all always-on? Is anything ever present in your chain? At a guess, I'd think the Hyper Luminal, and the SV. What role were you hoping the DCX to achieve? Low gain/tone sweetening seems to be
de rigeur with that pedal, but again, I find it pretty versatile, so maybe that wasn't your aim either.
