Independent shopping perspective
The Korena take
The Spectra Bass JS3QV is a 35-inch-scale, five-string bass with an offset poplar body, quilt veneer top, and a large upper horn intended to distribute weight and reduce neck dive. Dual passive medium-output humbuckers feed a blend control, coil-split toggle, and active-only three-band EQ. Pulling the volume control bypasses that active circuit, so the bass can still produce sound without battery power. Its bolt-on, graphite-reinforced maple neck carries 24 frets on a 12–16-inch compound-radius laurel fingerboard.
Strong match
Who this is for
- Five-string bass parts that need access across a 35-inch scale and 24-fret fingerboard.
- Long playing sessions where the offset body and enlarged upper horn are intended to reduce neck dive.
- Dialing pickup blends, coil-split settings, and active low, mid, and high EQ controls.
Consider the trade-offs
When to look elsewhere
- Players who need a four-string bass.
- Left-handed players.
