isn't a guitar dropped down an octave just, well,... a bass?
In technical pitch but a guitars EQ + amp + pickups etc = completley different sound obviously.
That's why I posted the pic of the 6-string bass.
A guitar tuned that low probable sounds flabby unless you use actual bass strings. I'm also wondering about intonation problems.
normal guitar speakers aren't designed for those frequencies.
At some point someone will have a (bass)guitar tuned so low you won't be able to hear it.
