Harley Benton R-458BK MultiScale

For less than the price of a basic 6-string Squire, this guitar is amazing. If you're looking for an 8-string fanned-fret metal machine, this is seriously worth considering.

Electronics: This is the weak point, but for the price, this shouldn't be a surprise. It has dime pots and the tone control works like a switch. The neck pickup is extremely muddy with the low notes, but has a really nice round tone in the upper octave. The bridge pickup, however, is nice and bright across the whole sonic range. The switch and jack are noiseless and the soldering seems solid.

Neck: This has a shallow D neck similar to my Warwick corvette 6 string bass, which is a profile I really like. The fretwork is surprisingly nice, but not perfect. The ends are rounded and there are no sharp edges, similar to the work you find on a low-end Schecter. The frets could, however, have been polished up a little more, and I found a few that could be re-crowned. The rosewood on the fingerboard was BONE DRY when I got it and it took two applications of lemon oil to get it looking healthy and happy. The back of the neck is sealed, but not coated in lacquer--again, a choice I'm pleased with. The action was pretty good out of the box and it was 1/2 step out of tune. I like my action as low as possible, and a quick truss rod and saddle adjustment made it really easy to play. This is my first fanned-fret guitar, and I'm hooked. If it were in charge of design, I'd have left the neck free from fret markers, or done something more interesting, but the jumbo dots all on one side are fine. The strings it comes with are WAY too light for an 8 string. I put on some 11-80 NYXLs and they feel great. The nut is really sharp on the edges, but a fine file fixed that for me. Weirdly, the cuts in the nut for the low strings are not parallel to the fretboard - they are higher on the headstock side and lower on the fretboard side.

Body: It currently only comes in black and white, which is...boring. I have a white Schecter 7 string, so I opted for the all-black. The electronics cavity cover is, surprisingly, just as shiny as the body once you take the plastic off, which is a nice touch. The finish had some fine swirly scratches behind the bridge, but I plan to refinish it with color-shift paint, so I'm not worried about them. The body is quite small, thin, and light compared to my Schecter. The contours are really nice and it's no work at all to hit the 24th fret.

Final thoughts: This guitar is amazing for the money. The quality is incredible and it's nice to see that corners weren't cut with the neck, fretwork, and playability. Cheap electronics are to be expected, but they do the job and swapping them out is a relatively easy task. If you're considering an 8 string, this is a great choice.

I bought this guitar mostly for fun, but also to experiment with extended range tunings, during the Covid-19 lockdown for £138 inc shipping. It took a while to get here, but I wasn't disappointed!

Having read the other reviews here and from watching demos on You-Tube, I was expecting to have issues with pickups, frets and tuners, but it I may have got lucky with 2 out of 3.
Mine was almost playable, right out of the box (nearly in tune!) with only an adjustment to the intonation on 1 string and tightening the tuners required to get up and running.

Starting at the top:

Headstock
The pearlescent Harley Benton logo has been moved in-between the 4-a-side tuners; an improvement from previous models, where it was stuck at the very end.
The tuners are unbranded and non-locking but once tightened up should function well enough. Considering it's a fixed bridge guitar, you wouldn't expect tuning stability issues, but all the strings are angled at the nut and this caused my D string to stick slightly, so mine will need re-filed. (While I'm at it I may just replace it for a black graphite type nut, as the white one looks a bit out of place)
The strings that came on the guitar are pretty decent, although they are lighter than the 10s mentioned in the specification

Neck
The C-profile is comfortable with a fast non-stick, satin finish and a tidy scarf joint between the 1st and 3rd frets. Slight neck-relief helps with bends and stops the F# string from rattling off the frets. The fingerboard is excellent, but a little dry and will need oiled, with offset dot-markers (3 at the 24th fret but only 1 at the 12th). On my example, the fret-ends had been well filed, with no sharp edges and the frets were well levelled for a low, buzz-free action, without any dead spots.
On the down side however, after levelling, the frets have not been crowned or polished, leaving them feeling pretty rough and scratchy on the strings.

Body
The neck/body joint is tight and well constructed with 5 bolts and a rounded heel. Access to the top frets is unrestricted and comfortable.
The black gloss finish was pretty good, although I had a couple of tiny dents and scratches and you can make out a bit of orange peel if you hold it to the light.

Pick-ups/Electronics
A lot of people complained of muddy sounding pick-ups with this guitar. Looks like it has been addressed by ditching the pre-amp and going passive, because my example sounds great, on both clean and hi-gain settings.
The huge shielded control cavity seems empty considering it now only houses 1 500K volume, 1 tone control and 1 three-way selector, but I suppose it keeps the weight down and maybe adds some resonance.
I've yet to remove the pups, so I don't know if there's a connection available for a coil-tap, but if so, I'd change out the 3-way switch for a 5-way.

Bridge
On this guitar there are 8 individual bridges, each with their own intonation and string height adjustment. They are well rounded and comfortable for palm muting. Strings are routed through body and the ferrules are all standard guitar-string size, so if you want to use bass strings for the F# and B, you'll need to get do some modification.

All-in-all for the price, this a suprisingly playable guitar which could easily be made gig-able by tweaking the frets, nut and tuners. I know a lot of people are buying this as a cheap alternative to Ibanez/Jackson/Schecter and adding in custom pick-ups, which often cost more than the guitar itself. This might not be necessary any more to get a decent sound. Without the active electronics muddying everything up, with a bit of tweaking of your amp's EQ settings, this beast is capable of suprising tonal variety, from djent to djazz!

Not a bad guitar for a first time 8 stringer, but there are some serious flaws.
First the bad:
1. Several people have mentioned the pickups being garbage, and they are totally garbage. They have a bad buzz/hum when the guitar is not being played or when long-sustained notes are played. Anything low-low mid volume that you want to play will have this buzz/hum present. Luckily, EMG makes several 8 string pickups that easily fit this guitar, but for a pair it costs more than the guitar.
2. The tuners are bad! They don't wind up smoothly and evenly. Also, they lose tune easily with the thicker strings.
3. Here's the big one: the guitar I was sent has a raised fret on the 16th fret and it could've been easily caught in the inspection that Harley Benton claims was done. It causes a nasty fret buzz sound on most of the strings from the 13th fret to the 15th. I can see the raised fret looking down the neck and I wish so badly that somebody would've caught that before sending it to me, because i have to exchange it and hope that the next one doesn't have the fretbuzz.

The good:
1. It's an insanely good deal for the money and I have no clue how they make a profit!? for the neck and body alone, It would be worth the same price. Adding a set of high quality tuners and pickups would cost 2x the guitar, making it something that could be played at shows, band practice and on basic recordings.
2. The neck and body feel great, very smooth and easy to play. I've played mostly 7 strings and 8 string guitars, this one fit right in with any of them. The fanned fretboard is smoothly playable and the fret edges were fantastic. My only complaint was the raised fret and hopefully an exchange will fix this.
3. It's easy to set the guitar up to the right levels. Dialing in the specific adjustments took very little time. I like to try different tunings and string gauges, so this easy adjustment is important.

My advice: This guitar is excellent if you're new-intermediate and want to test the waters with 8 string. If you're a regular player-professional then be prepared for some disappointment and/or after-market work.
