Because you are running the NUX MG-400 into the NUX Mighty 20, set the Mighty 20 to its cleanest channel with flat EQ to let the multi-FX amp block act as the sole high-gain engine. Urbandub's wall-of-sound rhythm relies on a boosted high-gain American rectifier voice; pushing the MG-400's middle to 6 compensates for your P90's naturally grittier, less compressed response compared to humbuckers. Tune the guitar down to Drop C# (C# G# C# F# A# D#) to match the record's low-end tension and voicing. Clean verse/intro: roll the guitar volume down to 6 and bypass the MG-400 boost block.
