YAMAHA DD-3 Digital Percussion (1993)
The smallest of Yamaha’s Digital Percussion Series.
For fun, practice, mobile use or circuit bending.

For each pad you can choose from 20 sound categories. Besides the basic sounds like Drum, Bass, Synth or other instruments, there are also some Fun/FX sounds.
The 12-button set also functions as keyboard for playing the instruments.

Much fun for small money.
Judging by the as-new condition of the pads, hardly used. Tested and found in excellent working condition.
