Donner DSJ-100 ST
A two-thirds-size electric guitar with a real alder body and maple neck, sold as a complete kit with amp, bag, tuner, strap and cable — and refreshingly honest about what a 500 mm scale does to tuning.
A properly built small guitar, not a toy — but the short scale is a trade, not a free lunch
Donner spent the money on wood and hardware, bundled everything a beginner needs, and then printed the honest caveat on its own product images. That last part is rarer than the guitar.
Alder body, maple neck with a C profile, maple fretboard, single-coil pickup and a stable fixed bridge — real guitar construction at 31.9 inches overall, with an amp, gig bag, clip-on tuner, strap, cable, spare strings and picks in the box for $125.99. The catch is physics: a 500 mm scale means low string tension, and Donner itself recommends tuning up a tone to keep the pitch stable.
Right for
- Children and smaller-framed beginners who cannot reach around a full-size body
- A first electric where the parent wants one box and no further shopping
- Adults who want a couch, travel or desk guitar that is genuinely small
- Anyone who values real wood and a working setup over brand names
Wrong for
- Players who want standard E tuning to hold rock-solid without adjustment
- Anyone expecting full-size tone and sustain from a two-thirds-size body
- Intermediate players wanting pickup switching and tone control
- Buyers who want to grow into the instrument — this one is outgrown, not adjusted
+What it gets right
- Real tonewoods. Alder body with a matte finish and a maple neck — the same materials logic as guitars costing several times more, not plywood with a picture of wood on it.
- Maple fretboard and a C-shape neck. The C profile is the standard beginner-friendly shape, and small hands reach across it easily.
- The kit is actually complete. Mini amp, gig bag, clip-on tuner, strap, cable, spare string set, four picks, polishing cloth and a truss-rod wrench. Nothing else to buy on day one.
- The included amp has real controls — gain, volume and tone, plus a headphone output and an AUX input, so a child can practise silently or play along to a phone.
- Fixed bridge with individual saddles. No tremolo means no tuning instability from the bridge — the right call on a beginner instrument.
- Three colours (red, black, green) at the same price, and free shipping with a 30-day return window.
- Donner publishes the short-scale caveat itself, including the recommended alternate tuning. That honesty is worth more than a marketing claim.
−Where it slips
- 500 mm scale means low string tension. Donner states plainly that pitch can be unstable in standard tuning and recommends going up one or two semitones.
- One pickup, one knob. A single volume control, no tone control and no pickup selector — you get one voice.
- Short scale, short sustain. A small body and short strings cannot produce full-size resonance. It sounds like what it is.
- Amp wattage is not published on the listing, so treat it as a practice amp for a bedroom and nothing more.
- Budget hardware. Vintage-style tuners at this price will need retuning often, especially while new strings settle.
- Expect a setup. At this price the factory action and intonation are a starting point, not a finished job.
- It is a stepping stone. A committed player will want a full-scale guitar within a year or two.
Scored as a first guitar, not as a guitar
The question for an instrument like this is not whether it competes with a full-size electric — it cannot. It is whether it removes the reasons a beginner quits: unplayable action, nothing to plug into, and a body they cannot get their arm around.
The long version
What the spec sheet means once it is out of the bag and plugged in.
Size & who it fits
The DSJ-100 ST measures 31.9 inches overall with a body 9.65 inches across — roughly two-thirds the footprint of a Stratocaster. The listing calls it a 30-inch junior guitar; the figure Donner prints on its own diagram is 31.9 inches end to end, and the number that actually matters is the 500 mm scale length between nut and bridge.
That geometry solves the specific problem that makes children give up on electric guitars: on a full-size instrument, a small player cannot get their strumming arm over the body and their fretting hand to the first fret at the same time. Shrink the body and shorten the scale and the guitar stops fighting them. Frets sit closer together, so small fingers can form a chord without stretching, and the whole thing weighs little enough to hold for a full practice session.
Body, neck & hardware
The body is alder with a matte finish — the same wood used on a great many serious electric guitars, chosen for a balanced tone rather than because it was cheapest. The neck and fretboard are both maple, cut to a C-shape profile, which is the standard shape for a reason: it suits almost every hand and gives a beginner nothing to fight.
Hardware is simple and correct for the job. A fixed bridge with individual saddles means intonation can be set properly and, crucially, there is no tremolo to knock the guitar out of tune every time a learner leans on it. Tuning is handled by vintage-style machines — functional, and the part of the guitar most obviously built to a price. Expect to retune often while the strings are new, which is true of any new guitar and more true of this one.
The short-scale trade
This is the section to read before buying. String tension is a function of scale length, string gauge and pitch. Shorten the scale to 500 mm and hold the pitch and gauge constant, and tension drops. Lower tension means a slinkier, easier feel — genuinely helpful for a beginner’s fingers — but it also means the strings are less stable, so the guitar drifts out of tune more readily and notes can go slightly sharp under a firm fret.
What is unusual is that Donner prints this on the product images itself. Their note explains that mini guitars use a shorter 500 mm scale so tension is lower than a normal electric, which may lead to unstable pitch, and recommends tuning up one or two semitones to restore tension. The diagram shows standard EADGBE going up to A♭ C♯ F♯ B E♭ A. They also state outright that more demanding players should buy a full-size DST-100, 152 or 400 instead.
Pickup & tone
One single-coil pickup and one volume knob. No tone control, no pickup selector. Plugged in, that gives a bright, thin, clean sound that takes gain reasonably well through the included amp — entirely adequate for learning chords, riffs and scales, and honestly a little charming through a small speaker.
What you do not get is variety. There is no neck pickup to switch to for something warmer, and no tone knob to roll the treble off. Combined with the short scale and small body, sustain is modest and the low strings lack weight. None of this is a defect; it is what a two-thirds-size guitar with one pickup sounds like. It becomes a limitation only when the player starts wanting a second sound — which is also the moment they are ready for a full-size instrument.
What is in the box
The kit is the strongest part of the proposition. Alongside the guitar you get a mini practice amplifier, a padded gig bag, a clip-on tuner, a strap, an instrument cable, a spare set of strings, four picks, a polishing cloth and a truss-rod wrench. Donner also bundles access to its free online beginner courses through the Donner Musa app.
The amp deserves a specific mention because bundled amps are usually where these kits cheat. This one has gain, volume and tone controls, a headphone output and an AUX input. The headphone jack is the feature parents will care about; the AUX input means the player can practise over a backing track from a phone through the same speaker. Donner does not publish a wattage for it on this listing, so treat it as a bedroom practice amp and no more — but it is a real amplifier with real controls, not a buzzing box.
Who should skip it
Anyone buying a guitar the player is meant to grow into. A junior guitar is outgrown, not adjusted — there is no way to lengthen the scale later. If the player is close to full size already, or is a determined adult beginner, the money is better spent on a full-scale starter guitar, and Donner will tell you the same thing in their own product note.
Also skip it if rock-solid standard tuning is non-negotiable, or if the player already knows they want humbuckers, a tremolo or pickup switching. This guitar does one thing, and it does it for one kind of player.

Against the obvious alternatives
Junior electrics split three ways: short-scale minis, three-quarter-size guitars, and full-size starter packs. The right answer depends entirely on how big the player is.
| Option | Scale | Body wood | Pickups | Kit included | Best for |
|---|---|---|---|---|---|
| Donner DSJ-100 ST | 500 mm (mini) | Alder | 1 × single-coil | Full kit + amp | Youngest beginners, travel guitar |
| Three-quarter-size starter electric | ~578–600 mm | Varies | Usually 2–3 | Sometimes | Older children, tweens |
| Full-size starter pack (e.g. Donner DST-100) | ~648 mm | Varies | Typically 3 single-coil | Often | Teens and adult beginners |
The short reading: buy the mini only if the player is genuinely small. The 500 mm scale is a real advantage for a child and a real compromise for anyone else, and there is no middle setting. If you are unsure, measure the player rather than guessing — the wrong size is the single most common reason a first guitar ends up in a cupboard.

The right first guitar for a small player, and honest about being nothing else
Donner built this out of alder and maple, gave it a fixed bridge and a C-profile neck, and packed an amp with real controls, a gig bag, a tuner and everything else a beginner needs into a $125.99 box. As a way to get a child playing this weekend rather than in three purchases’ time, it is very hard to fault.
The 500 mm scale is the whole product and the whole caveat. It makes the guitar reachable for small hands and it makes standard tuning less stable — a trade Donner documents on its own product images, along with the advice to buy full-size if the player is bigger. Take them at their word: measure the player first, and if the answer is small, buy this.

How this review was put together
This is a specification-based review. Price, colours, warranty, returns and shipping come from Donner’s US product listing, read on 24 August 2026. The construction details — alder body, maple neck and fretboard, C-shape profile, single-coil pickup, fixed bridge, 31.9 inch length, 9.65 inch body width and the 500 mm scale note with its recommended alternate tuning — are taken from Donner’s own specification diagrams published on that listing, because the listing text itself does not carry a specification table. Where Donner does not publish a figure, such as the included amplifier’s wattage, this review says so rather than estimating. Nothing here is based on playing the instrument.
