What is the scale 27" ??? I have a Fender Jaguar Bass VI and it is 30" which allows tuning one octave lower than a standard guitar tuning starting from low E. It is very different than pitch shifting. The tension and the organic sound without no errant tracking anomalies. Instantly inspiring to be at a new lower pitch and tension. My Low E is at .095 - The guages set is .025, .035, .045, .055, .075, .095. I guaranty you that this guitar will get you where you want to be sonically but it only has six strings. If your guitar can handle the tension, maybe the lower tuning and big fat strings will get you there. You may want to talk with your local tech for advise as this could require nut work and truss adjustment and might just not be suitable for your particular guitar. The tension will be considerable. My fingers got very tough and strong (see my photo to the left - the got all deformed - JK )doing cords on these strings - takes some getting used to for sure.
