Harley Benton Custom Line ResoKing BK review

The Harley Benton Custom Line ResoKing BK is a resonator guitar built in a compact electric-guitar format. Its slim body and two pickup types make it an unusual option for slide players who want to plug in, record, or practice at home without the bulk and volume of a full-size resonator. At a listed price of $235, it is an affordable way to explore the instrument's metallic, cutting voice, though buyer reports show that setup and quality control can vary.

The construction pairs a linden body with a poplar top, a set-in maple neck, and a laurel fingerboard. The neck has a C profile, a 43 mm nut, and a 648 mm scale length. There are 21 frets, dot inlays, body binding, and a double-action truss rod. The black, high-gloss finish gives the guitar a bold look, while its approximately 3.7 kg weight is substantial for its compact size. No case or gig bag is included.

Feel, setup, and construction

Many owners describe a comfortable neck, good balance with a strap, and an instrument that is easy to handle compared with a traditional resonator. The shallow body is a practical advantage for seated playing and smaller rooms. Some players report receiving an instrument that was close to playable straight from the box. Others found problems with fret ends, tuning hardware, paint, the nut, or the resonator assembly. Those contrasting experiences make a careful inspection on arrival worthwhile.

Setup needs depend on the guitar and playing style. The factory strings are listed as.011 to.052, but some slide players prefer a heavier set to increase tension and help the strings sit more firmly against the resonator bridge. Several owners report a fuller response and improved slide feel after changing strings. That is not a guaranteed fix for every buzz or setup issue. Check the action, neck relief, and intonation before making changes, and consider having a technician set it up if you are not comfortable adjusting it yourself.

The nut draws particular criticism in some reports. A poorly cut or low nut can affect string height and make slide playing harder, while other owners found their instruments ready to play. Tuning stability also gets mixed feedback. The die-cast tuners work, but some players describe stiff movement or uneven response while tuning. The string retainer can contribute to that sensation. Take time to bring each string up to pitch gradually and check tuning again after playing.

Two pickups, two different voices

The ResoKing's pickup system combines a mini humbucker with a piezo pickup, controlled by two volume knobs and one tone knob. The magnetic pickup generally supplies a rounder, thicker electric-guitar sound. The piezo adds a brighter, sharper attack that can suggest the resonator's metallic character. Blending the two is the central attraction: the balance can move from a smooth electric tone toward a more pointed, percussive sound.

Results are not consistent across all reports. Some players find the piezo too quiet beside the humbucker; others find it very strong or overly bright. The magnetic pickup can also sound dark on its own. The controls offer useful range, but several owners say their response is difficult to judge, with a large change near the top of the dial. There is no active preamp, so the piezo does not require a battery. If you plan to record directly or play at higher volume, test the output with your own amplifier or interface. A preamp may help balance the piezo, but it is an optional modification, not a factory feature.

Acoustic character and best uses

Unplugged, the ResoKing delivers a resonator-flavored sound at a lower volume than a full-size acoustic resonator. Its shallow body limits the sense of bass and projection, a tradeoff that suits apartment practice and controlled recording sessions. Owners describe the acoustic voice in different ways, from banjo-like and metallic to relatively quiet or thin. It can work for slide practice, open tunings, and distinctive studio parts, but it will not provide the room-filling acoustic output of a larger resonator.

Plugged in, the guitar can cover more ground. Players report usable blues and roots tones, with the humbucker handling a warmer electric voice and the piezo adding edge. At higher gain or volume, feedback and piezo harshness may need attention. The instrument's character also depends on string choice, setup, pickup balance, and amplifier settings, so expect some experimentation rather than one fixed sound.

Verdict

The Harley Benton Custom Line ResoKing BK offers an appealing entry into resonator and slide playing, especially for musicians who want a compact instrument with both magnetic and piezo pickup options. Its looks, manageable size, and blendable tones are compelling at the price. The main cautions are variable factory setup, inconsistent reports about hardware and finish, and a sound that is quieter unplugged than a full-size resonator. Budget time to inspect and adjust it, and allow for heavier strings if your slide style calls for them. For a player seeking an affordable, characterful instrument for home use, recording, or occasional stage work, it is a promising choice with some setup uncertainty.

Scores by area

Where it shines, where it stumbles

What convinced me

  • Distinctive resonator character, with useful tonal contrast between the mini humbucker and piezo pickup
  • Comfortable, compact design that many owners found enjoyable for slide and standard playing
  • Strong value for an affordable way to explore resonator sounds

What bugged me

  • Factory setup and quality control vary; some owners reported fret, finish, bridge, or hardware issues
  • The slim body produces less acoustic volume and fullness than a traditional resonator guitar
  • The piezo and humbucker can differ noticeably in output and tone, and the controls may take time to balance

Is it the right one for you?

Good pick if

A good fit for budget-conscious players exploring slide, blues, or resonator tones, and for home recording or amplified use. Also appealing to players who enjoy adjusting strings, setup, and pickup balance to suit their style.

Look elsewhere if

Not ideal for players who need strong unplugged projection or the fuller acoustic sound of a traditional resonator. Look elsewhere if you expect flawless factory setup, premium hardware, or consistent finish quality.

What other players say

Customer feedback is largely favorable about the ResoKing BK's appearance, distinctive resonator character, playability, and low price. Many owners enjoy the contrast between its piezo and mini humbucker, especially for blues, slide, recording, and amplified use. Some report that their guitar arrived well set up, while others describe inconsistent quality control, tuning or control issues, cosmetic flaws, or a need for setup work and heavier strings. Unplugged volume and fullness are commonly described as limited compared with a traditional resonator.

Before you decide

Questions players ask

Is the ResoKing BK suitable for slide playing?

Yes. Many owners use it for slide and alternate tunings. The factory string gauge and action may not suit every player, so a setup or heavier strings may help.

Does it sound loud when played unplugged?

It produces a resonator-like sound, but its slim body is quieter and less full than a traditional resonator guitar. It is better suited to home practice or amplified use than to high acoustic volume.

What do the two pickups add?

The piezo provides a bright, sharp resonator character, while the mini humbucker is generally warmer and fuller. Blending them expands the available tones, but their output balance can vary.

Should I expect to adjust the guitar after delivery?

Possibly. Reviews range from instruments that were ready to play to examples needing setup, fret attention, string changes, or hardware fixes. Inspect the guitar on arrival and assess its action and tuning stability.

Is it a good choice for a first resonator guitar?

It can be a good budget introduction for players interested in slide and amplified resonator sounds. It is less suitable if you expect traditional acoustic projection, consistent factory setup, or premium hardware.

The last word from the bench

At this price, the ResoKing BK is an appealing instrument for blues, slide, recording, and experimentation with resonator tones. Its mini humbucker and piezo provide contrasting sounds, though their levels and character may need careful adjustment. Customer experiences with setup and finish are inconsistent, and some instruments benefit from heavier strings or further setup work. Buy it for its unusual sound and value, not for the uniform finish or acoustic projection of a traditional resonator.
