Yes, there are bass ukuleles, and despite their late arrival, they were a big hit. They're smaller than a bass guitar but provide a big, powerful sound, akin to electronic drums.
Although it is modest in comparison to a guitar, it is the largest ukulele in the line, with a typical total length of 76.2 - 81.28 cm (30 - 32 inches). The smaller ones are bass guitars that play the same notes as a conventional bass guitar but one octave higher, whereas the double bass guitars are the largest and play in the same octave as a bass guitar.
Bass strings, Mi / La / Re / Sol, are thicker. For increased power during concerts, electric models can contain passive or active piezo dosages that enhance the sound before the combo.
