The 2025 Ibanez catalog no longer has the Mezzo listed. Of course there are a bunch still for sale at retailers, but apparently it wasn't a big enough seller to continue.
The Mezzo came around at a perfect time for me. It's light, inexpensive, and sounds great (especially with an Audere preamp). The B string on my 5s sounds consistent with the other strings. Introduced in 2019, they had a bunch of colors for the 4 string and only a couple for 5. I'd say I'll miss them... but I won't 'cause I have two 5s and a 4 string.
The only downside for those basses is the B string on the 5. It sounds great with the stock strings, which are the D'Addario EXL165 long scale for the first 4 strings, but the B has to be medium scale to keep the winding off the tuner post. Apparently the B string was specially made for that bass by D'Addario, and only supplied to the Ibanez factory (product code XLB130m). I had a pretty difficult time locating additional B strings. I had to communicate a bunch with both Ibanez and D'Addario, finally getting them to provide them to some (?) retailers. I ended up with five of the special strings, but have not seen any more anywhere. It's okay- I'll outlive my B strings.
