Harley Benton Fusion-IV HH RW FR WM review

The Harley Benton Fusion-IV HH RW FR WM has an appealing specification sheet for a guitar priced at 477. Its white metallic finish, rosewood fingerboard, roasted flamed maple neck, stainless steel frets, and Floyd Rose tremolo suggest a feature-rich instrument. The combination looks especially promising for players who want a modern double-cut guitar with two humbuckers and a locking tremolo. But the reported experience with the instrument raises a more basic question: how well were its parts fitted and adjusted?

The guitar has a nyatoh body with natural wood binding and a bolt-on Canadian roasted flamed maple neck. A Modern C profile measures 21 mm at the first fret and 23 mm at the twelfth. The 648 mm scale is a familiar full-length format, while the compound fingerboard radius runs from 305 to 406 mm. Harley Benton lists 22 medium-jumbo stainless steel frets, a Graph Tech TUSQ XL nut, circular fingerboard inlays, and glow-in-the-dark side markers. The reported fretwork was very good, and the rosewood board and inlays drew positive comments. The finish also received favorable feedback.

Pickup options and switching

A Tesla Opus-1B Alnico 5 humbucker sits at the bridge, with an Opus-1N Alnico 5 humbucker at the neck. The controls comprise one volume knob, one tone knob, a five-way switch, and a mini-switch described as an alter switch for the Ghost coil. The bridge pickup was judged acceptable, while the neck pickup sounded somewhat muddy with the alter switch off. Pickups are replaceable, so that tonal impression may matter less to players already planning an electronics change.

The more serious concern involved the alter switch. In the reported test, engaging it added excessive high frequencies and substantial noise, making the setting effectively unusable. That is a significant limitation for a feature intended to expand the guitar's available sounds. The other pickup sounds were considered usable, but the switch's unwanted noise undermined its practical value. Buyers should treat this as a report about the tested instrument, not proof that every Fusion-IV will behave identically.

Neck adjustment and tremolo concerns

The strongest warning in the field notes concerns the neck setup and tremolo hardware. The neck arrived with too much relief. When the reviewer attempted a small adjustment, the truss rod felt exceptionally stiff, as if it were already close to its limit. Loud cracking noises followed when using the Floyd Rose tremolo. The reviewer suspected that the noise came from a sudden release of tension on the truss rod, but the precise cause was not confirmed.

There was also a reported fit issue at one of the bridge-stud inserts. Its drilled opening was said to be oversized, with a shim used to compensate. That observation, combined with the stiff adjustment and cracking sounds, points to concerns that go beyond personal preference or pickup voicing. A tremolo guitar depends on stable, correctly fitted hardware and a neck that can be adjusted safely. Anyone hearing similar noises should stop using the tremolo and have the instrument inspected by a qualified technician rather than force the adjustment.

Upper-fret access and design choices

The Fusion-IV has 22 frets, whereas the reviewer's comparison point, the earlier Fusion III FR, had 24. The shorter fret count was viewed as a step backward, and access to the upper frets was described as limited. Players who regularly use the highest positions should try the neck in person if possible. The available information does not establish that every player will find access difficult, but the change in fret count is worth noting for anyone comparing the two models.

Other listed details include black hardware, Jinho JN-03M tuners bearing the Harley Benton logo, and coated Harley Benton HQS strings in.010 to.046 gauges. The guitar is sold without a bag or case. It has been listed since April 2026 under item number 618126.

Verdict

The Harley Benton Fusion-IV HH RW FR WM offers a strong collection of components on paper, and the reported fretwork, fingerboard appearance, inlays, and finish are clear positives. Its pickup layout provides several switching options, and the full-length scale and stainless steel frets will suit players looking for a modern specification.

However, the test account describes problems that deserve attention before purchase: a noisy alter-switch setting, a very stiff truss rod, cracking sounds during tremolo use, and a questionable bridge-stud insert fit. These are not minor cosmetic complaints, especially on a guitar built around a Floyd Rose system. The sample's good fretwork and finish do not offset uncertainty about its setup and hardware installation. Inspect the tremolo, neck adjustment, and stud inserts carefully, or confirm the return and service arrangements before buying. Based on the reported instrument, this model is difficult to recommend without a thorough setup check.
