The HS1, an humbucker-sized, single-coil pickup on the DN400
Other pickups made by Ibanez which don't belong to any regular line. Most of them are pickups from the late 80's, mid 90's and not much is known about them.
Some of them are very exclusive pickups which are found on non-standard series.
Has one traditional coil and one with a blade. Can be found on the RG565 [It] delivers a "fat", harmonically active sound. The most powerful lead pickup in the American-Designed series.
A single-coil-sized humbucker, twin blade, which often comes along with the HB2 humbucker (see above). Can be used in the neck position, like the RG565 or in the middle and neck positions as seen on the RBM series (Reb Beach signatures), like the RBM1.
A single-coil-sized humbucker, twin blade like the SB1. Can be found in the neck/ mid position either with a SB1 in the bridge (on the 542R), or with Axis pickups in the bridge (on the FGM400, Frank Gambale's signature).
The tube pole-piece construction of the new pickups designed for the Ibanez Darkstone offers quick response, sparkling clarity and added harmonics for a humbucker sound. At the same time, humbucker-sized single-coil pickups were also introduced in the Darkstone series, the HS1 pickups (see below).
Humbucker-sized single-coil pickups introduced in 2009 in the Darkstone series, along with the PP1 pickups (see above). Only two models use the HS1, the DN400 and the DN600. [They] produce loud and crunchy tones that cut through for hard rock and punk styles.
Introduced in 2014 in the Destroyer series. Only one model uses the Classic Elite pickups so far, the DT420. (other Destroyer models of the same year use a couple of DiMarzio Air Norton and DiMarzio The Tone Zone, to give a tone and mood reference). [They] offer rich, nuanced tone with fat low-end..
