"PPG Wave 2.2 with midi installed. System software is V8.3. Includes custom dust cover and a custom wooden box for shipping. In great condition for its age, some minor scratches. Professionally serviced recently. Also, in 2016 I got it fully restored by a tech who specializes in PPGs. He installed the keyboard upgrade kit, replaced the battery, replaced lots of caps, including the power supply one, tuned the voice boards, and tested everything.
This PPG Wave 2.2 was used to make Goldbaby's BlueWave sample pack. Check out the pack by visiting the Goldbaby website."
