Initially sold for ¥59,800

The SPX50D is basically a SPX90 aimed at guitarists.

The main additions are a set of distortion effects, a digital tuner for guitars and support for being inserted within an effect loop. It incidentally dropped the support for a remote unit that the SPX90 had.

It's one of the few Yamaha boxes to feature a red retroilluminated LCD panel.
