Independent shopping perspective
The Korena take
The Spectra Bass JS23 is a four-string electric bass with an offset poplar body, bolt-on maple neck, and 34-inch scale. Its bound laurel fingerboard has a 12-inch radius and 24 medium frets. A J-style bridge pickup and P-style neck pickup feed master volume, blend, and active bass-boost controls, letting you combine the two pickup voices. The volume control’s push/pull selector engages or bypasses the active circuit. Finished in walnut stain with black hardware, it uses a Jackson HiMass bridge with individual saddles.
Strong match
Who this is for
- Four-string bass parts that call for blending the J-style bridge and P-style neck pickups.
- Players who want to engage or bypass the active bass-boost circuit from the volume control.
Consider the trade-offs
When to look elsewhere
- Purchases that require a case or gig bag to be included.
- Bassists looking for more than four strings.
