So the guitarist is coming with metal tunes in drop c. E standard down a whole step to d. then that d down to c. cool for djenty bared power chords. there is a couple drop d tunes i use a 4 string for. but this new c standard might be my metal go to, why tune down when you can tune up? before this metal jamming i was running e-c for chords and stuff but this new c-g# is sweet .. lots of tension on the C , i lost the little truss rod cover ages ago so that an easy adjustment. Anyone else using this tuning?
