8 string guitar but one octave lower

Thought G#0 was the limit... Downtuning the Ibanez M80M to F#0, a whole octave lower than the standard F# on 8 strings guitars. It has turned into something else. Still using D’addario NYXL0980 strings. Guitar: Ibanez M80M Meshuggah Signature - Neural DSP Archetype Nolly Bass: Impact Studios Avalanche Neural DSP Parallax Drums: GGD Modern and Massive
