This is the Korg P3 Piano Module from the original M1 time period in the 1980's. The M1 piano sound was used on countless recordings back then and the P3's two piano sounds are improved variations on that now classic sound.
In a rock band context the brighter Piano 1 will cut through, while the fuller sounding Piano 2 would be more suitable for other music. For a vintage 80's piano sound in recordings this will do the trick without having to find an expensive older Korg M1 or T series keyboard in good condition. The Korg P3 works fine and includes the power supply. It has a few scratches, that's all. I have the manual as a PDF file. The sounds can be split, transposed, etc, and the unit accepts add-on cards as well. Velocity response can also be adjusted.
I'm asking $100 cash only and pickup only. If you email me I'll get back to you ASAP.
