How it’s played

ringing open-tuned clean (bigger in choruses) distortion. This shapes how hard the amp is pushed and where the EQ sits for the Iris sound.

What makes the Iris part tricky

B-D-D-D-D-D tuning, open-string drone, strumming. GuitarToneAdapt gets the tone right so you can focus on the playing.

Note: Iris is in the special tuning B D D D D D — that open-string drone IS the sound. Play it through a loud, chimey amp, mostly CLEAN with reverb; the choruses get bigger and lightly driven. Without the tuning it won’t ring right., Retune to B D D D D D, use a bright chimey clean with reverb, let the open strings drone, and push to a fuller tone in the choruses., Settings are community-researched starting points, not official recall sheets.
