Independent shopping perspective
The Korena take
The Pro Series Spectra SBFM IV combines an offset four-string body with multi-laminate flame maple, walnut, and mahogany construction in a satin Chlorine Burst finish. Its enlarged upper horn is intended to spread the instrument’s weight while you play. Two Nordstrand SB4 soapbar pickups, blend control, three-band EQ, and selectable mid frequencies make the onboard controls especially broad. The neck-through five-piece maple/walnut neck carries a 24-jumbo-fret caramelized jatoba fingerboard with a 12–16-inch compound radius.
Strong match
Who this is for
- Extended live sets where the larger upper horn’s weight distribution and speed-neck contour are part of the design brief.
- Bass parts that require blending two pickups and targeting selectable midrange frequencies from the onboard controls.
- Players using the active EQ who want an active/passive toggle available on the instrument.
