  • Tone similar to a traditional uke
  • Preamp for volume, bass, mid, and treble control


The instrument’s materials and shape create a warm and soft sound, with a good balance of grind and bite. The pre-installed strings absorb less moisture than similar strings to ensure tuning stability and the gauged strings of varying densities provide increased accuracy of fret-intonation. The integrated tuner allows you to forget carrying around your own tuners and allows for greater accuracy in your tuning as the reading is directly from the preamp. This avoids problems with background noise and interference while making tuning effortless. This instrument sounds more like a low-pitched guitar than a uke. This is definitely an advantage when you are looking for a unique addition to your ensemble or solo play.

Ease of use and comfort

The UKB-23 (length: 29 3/4″) is rather large compared to a soprano ukulele (length: 21″), the type that you are likely most familiar with. While this seems like a large difference, this is still a very light instrument compared to the weight of most guitars. It is still designed to be a uke, but the larger size helps to lower the pitch to that of a baritone instrument. The thick, solid strings combined with short frets allows your fingers to glide over the frets without catching. All of these features make the UKB-23 is a very comfortable and easy instrument to play and enjoy.

    1. Hi Glen,
      It’s on of the best Bass Ukulele from Headen in this price range, so quality will be there and it should be close to the one you got now. Definitely not a bad ukulele to use, sound is very good compared to those other options in this price range.
      Thanks you for your question.
      Have a good day!
