The Spector REX 5 Holoflash features active EMG pickups that offer a wide tonal range and sound control.

The 35" scale length effectively tightens the low B string, preventing it from being floppy.

The bass excels in slap and fingerstyle, with a tone that surprised even traditional jazz bass players.

It's especially well-suited for rock and metal genres, aligning with Rex Brown's style and preferences.

Some users find accessing the lower frets challenging due to the pseudo cutaway design.

Some users experience neck dive when standing, but this can be mitigated with a wide, 3-4 inch leather strap to keep the bass stable.

Users transitioning from a Dean ML Metalman bass note the Spector REX 5 Pro as a noticeable upgrade for live performances.

One user successfully enhanced a lower-end Spector model by replacing EMG HZ pickups with EMG DCX and CSX models.

Users compare the body shape to the Ibanez Destroyer, noting familiarity for those transitioning from similar models.

Owners report that the bass has a super low action and wide string spacing, approximately 19mm at the bridge.

The Holoflash finish, popularized by Kramer in the 80s, is noted for its distinctive visual appeal.

Abalone block inlays may indicate a US model, contrasting with imported models that typically feature dot inlays.

The bass's extra wide body can make it awkward to hold, as the wrist position during plucking ends where the body typically does on standard basses.

Korean Rex Pro models, identifiable by dot inlays and a non-gold large solid brass bridge, are valued between $700-$1000 based on condition.

The Spector REX 5 model is considered rare, often priced between $700 and $900, making $750 a fair deal.
