I think this really illustrates nicely the benefits and challenges of switching from a re-entrant tuned ukulele to one with a Low G string.
The pluses are:
- a deeper sound (even if it’s just a little bit);
- often your major chords have a fuller sound (still doubling a note, but an octave apart is possible);
- a greater range — five extra notes’ worth!
On the other hand…
- some easy picking patterns become more difficult (the low G really stands out);
- most tabbed songs (for solo uke) assume a high g and you’ll need to do some on-the-fly thinkin’
At one point i would have included the string itself as a negative: until quite recently most low G strings were wrapped wire, just like a guitar string, and tended to wear out quickly. Not so now with Aquila’s reds or the Worth nylon low Gs.
All told I enjoy the sound my Low G (over reentrant tuning) adds to my mediocre playing.
