Key Features

Professional Reviews Summary

While major publications have yet to publish formal reviews of the SBX IV, gear specialists at Reverb highlight its impressive build quality and tonal flexibility, especially for the price. The neck-through construction and active/passive electronics are praised for offering features typically found in higher-end instruments ("Jackson X Series Spectra Bass SBX IV Electric Bass Guitar | Reverb"). However, the hardware—particularly the tuners and bridge—are noted as budget-tier components that may benefit from upgrades.

User Sentiment Summary

On TalkBass, users report that the SBX IV is comfortable, lightweight, and sonically versatile, with standout sustain and a fast neck ("NBD!!! Jackson Spectra SBX IV!"). The pickups are described as punchy and articulate, especially in coil-split mode. However, several users mention sharp fret ends, cheap tuners, and muddy tone in full humbucking mode unless EQ’d or modified ("Jackson Spectra: details, electronics, and some fixes/upgrades"). One user even re-engineered the electronics to improve clarity and reduce hum, suggesting that while the bass is mod-friendly, it may require tweaks to reach its full potential.

Pros:

  • Neck-through construction offers excellent sustain
  • Active/passive electronics provide tonal flexibility
  • Coil-splitting adds versatility for modern and vintage tones
  • Comfortable body shape and compound-radius fretboard
  • Affordable price for feature set

Cons:

  • Tuners and bridge are low-end and may require upgrades
  • Fret ends can be sharp out of the box
  • Passive mode lacks tone shaping (no tone cap)
  • Coil-split mode introduces hum unless pickups are blended

Ideal For

This bass is perfect for intermediate to advanced players who want a mod-friendly, gig-ready instrument with modern features. It suits genres from rock and metal to funk and fusion, especially for those who value tonal flexibility and neck-through sustain.
