I've never tuned my Jazzmaster down that far, might have to give it a shot since it seems to work for Troy.
Also, Theodore's floor tom in the chorus sounds fucking massive!
whenever ive wanted to play anything below C ive either bought (slightly) thicker strings or just used my bro's ibanez, but i rarely ever do as im not a fan of low tunings.
& i really think the drums on this upcoming record are going to be just out of this world. Theyve always had drums that sound massive but with 3 supposed drummers on it i can see there being an extra emphasis on drums maybe?
