Harley Benton Fusion-IV HH RW FR BM

Harley Benton Fusion-IV HH RW FR BM: Technical Review

The Harley Benton Fusion-IV HH RW FR BM is a solid-body electric guitar with a dual-humbucker layout and a Floyd Rose FRT 1000 Original tremolo. Its listed price is 477, and it has been available since April 2026. The specifications describe a guitar aimed at players who want a locking tremolo, stainless-steel frets, and multiple pickup-switching options. They do not provide enough evidence to judge build consistency, tuning stability in use, or the sound of the instrument, so those points require hands-on testing.

Body, neck, and playing dimensions

The body is made from nyatoh and has a glossy Black Metallic finish. There is no separate top, while natural wood binding outlines the body. The neck is bolt-on roasted Canadian flamed maple, paired with a rosewood fingerboard. The neck profile is Modern C, measuring 21 mm thick at the first fret and 23 mm at the twelfth. Those measurements offer a more useful sense of the neck's shape than the profile label alone, though comfort remains a matter of individual preference.

The scale length is 648 mm, or 25.5 inches, and the nut width is 42 mm. The compound fingerboard radius moves from 305 mm at the lower end to 406 mm at the upper end, equivalent to 12 to 16 inches. In principle, that changing radius combines a rounder feel in the lower positions with a flatter surface higher up. The specification does not establish how the guitar is set up or how easily it bends notes across the fretboard.

There are 22 medium-jumbo stainless-steel frets, each specified at 2.7 mm. The fingerboard has circular inlays and glow-in-the-dark side markers. A double-action truss rod is adjusted using a wheel, a layout that makes the adjustment point accessible without describing the exact clearance or adjustment procedure. The nut is a Graph Tech TUSQ XL unit. No factory setup measurements, fretwork tolerances, or neck relief figures are supplied.

Pickups and controls

The pickup set consists of a white Tesla Opus-1B Alnico 5 humbucker at the bridge and a white Tesla Opus-1N Alnico 5 humbucker at the neck. The controls are one volume knob, one tone knob, and a five-way pickup selector. A mini-switch is identified as an alter switch for ghost coil. That description indicates additional coil-related switching, but the supplied specifications do not map each selector position or explain the mini-switch's full switching logic. Buyers should check the wiring diagram or test the controls directly if specific combinations matter to them.

Alnico 5 magnets and humbucker construction identify the pickup types, but they do not establish output level, frequency response, noise performance, or how the pickups balance with one another. There are no audio samples or measured electrical specifications in the provided information. The guitar's actual clean and high-gain character therefore cannot be determined from the component names alone.

Floyd Rose hardware and setup considerations

The tremolo is listed as a Floyd Rose FRT 1000 Original, with black hardware. The guitar also has Jinho JN-03M machine heads carrying the Harley Benton logo. The locking tremolo is a defining part of the instrument's specification, but it also makes string changes, tuning changes, and alternate tunings more involved than on a fixed-bridge guitar. The supplied details do not state whether a tremolo arm is included, how the bridge is set at the factory, or whether the nut and bridge are adjusted before shipment.

The strings are coated Harley Benton HQS EL strings in.010 to.046 gauge. That gauge is a useful reference for replacement strings and setup, particularly on a floating tremolo, where changing string tension can affect the bridge balance. The specifications do not say whether this is the gauge installed at the factory or whether the guitar ships with a different setup.

What the specifications do and do not establish

• Included accessories: No bag or case is included, so transport protection may need to be purchased separately.
• Finish and appearance: The listed finish is high-gloss Black Metallic, with natural wood body binding and white pickups.
• Item reference: The item number is 618124, and the sales unit is one piece.
• Unverified points: No customer reviews are available, and the supplied data gives no direct evidence about weight, balance, acoustic resonance, factory setup, or long-term reliability.

On paper, the Fusion-IV HH RW FR BM puts its emphasis on a roasted maple neck, stainless-steel frets, a compound-radius rosewood fingerboard, two Alnico 5 humbuckers, and a Floyd Rose locking tremolo. Those features make the specification substantial for players seeking that combination. The practical decision depends on details the data sheet cannot answer, especially the neck's feel, the switching behavior, the tremolo setup, and overall quality control. Since no customer feedback is available, this assessment is limited to the listed construction and hardware.
