The Ergodyne series is a line of solid body electric guitar (and bass guitar) models produced by Hoshino Gakki under the Ibanez brand. It was introduced in 1997 and discontinued in 2006. The entire series was offered only in Europe, though some individual models were also sold in Asia & South America.
The most notable feature of the Ergodyne models is the luthite body material, a synthetic material developed as a substitute for wood. All EDR models have a rounded body shape reminiscent of the the S series models or the Joe Satriani series. Late in the series run a model, the EXR170, was produced which eschewed luthite for wood but retained the Ergodyne shape.
Guitar models Edit
The first EDR guitar was the EDR260. It featured Ibanez Powersound pickups and a synchronized tremolo bridge. The EDR470 was introduced a year later and was a more deluxe version with Ibanez Axis pickups and a double locking tremolo. The most basic version was the EDR170 introduced in 2002, again with Powersound pickups and a synchronized tremolo. The EDR170EX and EDR470EX had "Designed by EMG" pickups.
In 2005, all luthite-bodied EDR models were discontinued. Instead, the wooden-bodied EXR170 was introduced, similar to the EDR170 but with an agathis body. The GXR370, also introduced in 2005, was another model based on the original Ergodyne guitar.
Bass models Edit
The Ergodyne series also featured a few 4 and 5 string bass guitar models which had three distinctive body shades. The Ibanez EDB series had two pickups (review) while the EDA and EDC models had a piezo bridge and a single pickup (review). The EDB is the oldest of the models. Most models were made with a man-made material called Luthite, but in 2006 they offered a wooden version of the EDB bass.
