Low-end GIO (entry level): PowerSound(PSND) series.
The domestic RG270 (note that RG is not GRG, and the bridge section of this model is Edge Pro) is also this pickup.
Low-end: The RG3XX series and RG4XX series produced in Indonesia mostly adopt the British finidi (INF) series pickup trucks.
Mid-range: RG 1XXX series in Nissan Prestige series adopts V8 S 1 V7 pickup truck produced by Ibana.
Except RG 1450 and RG 145 1, they all use V6F pickup trucks.
It seems that the high-end models of Preuium series (RG870 series) made in Indonesia also use V6F (I don't remember).
High-end: RG2XXX series, using the microphone produced by Ibana authorized by DiMarzio, a world-class microphone manufacturer.
Although it is marked DiMarzio, it is actually produced by Ibana, which is different from the original DiMarzio, just like Floyd Rose's certified piano bridge and the original piano bridge.
High-end: RG3XXX series, RG4570Z, etc. , using the original DiMarzio pickup (True Violet /The Zone/Air Norton).
However, this is just most pianos. Some pianos use other pickups, such as RG2620ZE, EMG pickup (this piano was re-produced at 20 12 before re-production, which seems to have a double-coil pickup), RG3520, and DMZ/IBZ pickup, RG 1620A.
S series:
The low-end S470, S570, these use INF.
Mid-range pickup trucks are uncertain (because the pickup trucks used in these mid-range models are very different, and it takes too much time to list them one by one).
The high-end S5470 series adopts a true Duo pickup, which is quite novel. It consists of a single coil and a small double pickup, and the working mode of the pickup can be controlled by the volume key.
SV series: Similar to S5470 series, except that the bridge pickup is replaced by the traditional double-coil pickup.
RGD series: RGD320/RGD420 uses a cam pickup (it seems that I have never touched this piano, but I have seen the pickup model once in official website, but I forgot it).
RGD8520 adopts V7 and V8 pickups specially improved by engineer Ibana, and the timbre is quite good.
RGA series: LZ series pickups are adopted, all of which are independently developed by Ibana.
Artist's signature: generally use the microphone designated by the artist, such as Evolution or Breed of Steve van, Paf Pro of Munky, etc. There are many low-end models that use INF, but some don't, such as MBM2, JS 100.
I know so much about Ibana guitar pickups, and there are many series I haven't said. I'm sorry I'm ignorant, because I haven't played those pianos, such as jazz guitar and les paul guitar, but Ibana's piano is really good, and the balance in all aspects is one of its advantages.
