Now, the upcoming HZB4 looks a bit better to me, though a 5-string would be preferable. The changes from the HNB5 are subtle e.g. the pickguard is not quite as mad and isn't under half the controls. The rear doesn't have a cavity all the way under the bridge. These pics are the Satin Silver (top) and Gloss Aura Pearl (rear) finishes, it's also expected in Satin Black.
