Detail 01
28.6-inch scale
Frets sit closer together, so stretches are easier and string tension is looser. Feel is floppier and tone slightly warmer than long scale.

- Guitarists picking up bass without relearning stretch
- A compact travel or couch bass that stays portable

What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
PJ pickup pair
P pickup at the neck for thick midrange, J at the bridge for bite. Blend the two volumes to move between them.
Detail 03
Individual volume, master tone
No pickup selector switch. You mix the two pickups by ear with their own volume knobs.
Detail 04
Poplar body
Light and tonally neutral, sitting closer to alder than ash. Comfortable weight for a small player.
Detail 05
Bound purpleheart fingerboard
Dense and hard, close to ebony in feel. Binding covers the fret ends so edges feel smoother.
Detail 06
38 mm nut width
Narrow spacing at the nut. Easy for small hands, tighter for fingerstyle players who want room between strings.
Final check
Know before you order
- 01Case and gig bag are sold separately
- 02Short scale usually needs short-scale strings — standard bass strings may not fit
- 03Expect a setup; looser short-scale tension makes intonation and action worth checking
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is a short-scale bass harder to play than a full-size?
Easier, generally. The 28.6-inch scale shortens fret spacing and lowers string tension, which reduces stretch and pressure for smaller hands.
02Can I use regular bass strings on it?
Not reliably. Short-scale sets are made for this length; long-scale strings can put the taper in the wrong spot at the nut or tuner.
03What does PJ mean?
One P-style split pickup at the neck and one J-style single at the bridge. The P gives thick mids, the J adds bite. Each has its own volume.
04Is it too small for an adult?
No. Adults use short scales for comfort and travel. The tradeoff is looser tension and slightly less low-end snap than a 34-inch bass.
