Advanced Specs that are even closer to those of Osamuraisans own guitar
String's gauge
Based on Elixir's Custom Light gauge, Osamurai himself changed the high E string to a 0.02 thicker string thickness compared to the regular size (0.11→ 0.13) and the B string to a 0.01 thicker one (0.15 → 0.16) in order to get a more rounded sound for an optimal setup to play melodies on those strings.
Pickups
Osamuraisan has a "RAPTOR SYSTEM" produced by the TRIAL brand installed in his HJ-523. The complete setup is comprised of a dual pickup system with RAPTOR SYSTEM’s original "body microphone" piezoelectric pickup, and the magnetic pickup SUNRIZE S2 that creates a high-quality dual system that works in combination with an external preamp.
