S.U.B. Ray4

In-brand default — Slinky Bass is the string this bass is voiced around and likely ships with from factory.

NYXL Bass's brighter top-end and tighter low-end help the SUB Ray4's single humbucker cut through band mixes more assertively.

The Jaco upgrade for active-bass players — stainless steel Swing 66 maximizes the SUB's 2-band preamp range into aggressive fusion territory.
