The 540RHH, which was also known as the 540R-HH, is a Radius series solid body electric guitar model introduced by Ibanez in 1988. It was made in Japan by FujiGen as part of the Roadstar Pro series.
The 540RHH was changed multiple times. In 1991 the Lo-Pro Edge tremolo was introduced and was used on the 540RHH along with the Edge for the Japanese market. In 1990 the pickup selection toggle moved from between the two pots to a spot closer to the volume pot. The JS models based on the 540RHH do have the toggle on the older spot.
The 540R is a similar model with a humbucker/ single/ single pickup configuration.
