At present, the IBANEZ pianos sold in the market are generally these series:
Sound equipment:
The LOGO of the piano head is large SDGR, and the next line is the small sound file of IBANEZ.
ERGODYNE: the LOGO on the head of the piano is big IBANEZ, and the next line is little ERGODYNE.
BTB: There is the symbol of BTB in the upper left corner of the piano head.
ATK: There is the symbol of ATK in the upper left corner of the piano head.
GSR: The symbol on the head of the piano is GIO IBANEZ.
Then there is the feel test. The feel of IBZ is slippery, which can't be compared with the ordinary fake piano. The neck of the piano is very thin. In terms of timbre, the timbre of IBZ is generally thin and bright, and the timbre of fake IBZ on the market is dark, so the high frequency can't come out at all.
Moreover, IBZ's double bass is equipped with instructions. If they are purchased from the Great Wall, some of them have Chinese instructions. There is an IBANEZ label on the carton, with IBANEZ LOGO on the front and your piano model and number on the back, just like the one on the back of the piano head.
