I don’t think anything more is needed. The guitar meets all the requirements. It’s a well-thought-out setup by Ibanez. On the other hand, you need to be very careful because it doesn’t really forgive mistakes when playing. It demands precision and seriousness from the guitarist as well. I had to make some adjustments since, for me, the string action was too high. The guitar allowed 1mm (high E) and 1.2mm (low E) without any issues. I adjusted the pickups to 4mm (this seemed to produce a balanced and correct sound when switching between the bridge and neck pickups).
A minor downside is that the volume and treble knobs slightly touch the edge of the cavity where they are housed. This will probably resolve itself over time. Other than that, it’s an excellent instrument.
