If it wasn't for this random YouTube video talking about fx pedals I wouldn't have gone and done some experimention lol

For the record it goes:

Guitar pickups set to middle position.

Overdrive to amp

In the fx loop:

Harmonic tremolo, wave set to saw up going into a space echo 1/4 note division, then into a basic reverb with mod turned up and predelay set to 10ms.

Pick inverted 2 note chords. Loop, then put guitar pickup into bridge position and tremolo pick single notes over the top.

Absolute heaven!!!!!
