Best neck-through 4-string electric bass guitars under $1,450

Top pick: Jackson X Series Spectra Bass SBXP IV — the only true neck-through 4-string here, and the one that gives you the sustain and upper-fret access you're after without spending near the top of your budget. Its poplar body and slim neck make it an easy all-rounder for rock and metal.

Who the others suit:

• Aria Pro II SB-700 — if you want a classic, more vintage-voiced bass and a step up in feel; it's the priciest of the real contenders.
• Schecter Stiletto Studio 4 — a comfortable, modern-feeling bass for players who care more about playability than neck-through construction (it's bolt-on, so it doesn't meet that spec).
• Yamaha TRB1004J — a 35-inch five-piece neck for players who want tight low B-style tension and a brighter, more modern tone; also not neck-through.
• Yamaha BB434 / TRBX304 — solid, affordable workhorses if you'd rather spend less and don't need neck-through.

If neck-through is non-negotiable, the Jackson is the one to buy.
