Alexander Hamilton etched in the mod wheel section.

Pics of the inside below.

"The unit appears to be working reasonably well with a few issues that need some repairing and servicing work for full function. I'm not a technician at these so I may have not covered every function, but here below are the issues I noticed as being tested.

Voice #8 fails autotune, as well as a few others occasionally fail randomly.

Hence the pitch seems slightly unstable.
The modulation bend lever appears to be not responding. The pitch bend is fine.
Has MIDI installed by the previous owner, where the "Computer Interface" slot been removed and the MIDI output/input coming out loose as pictured. The MIDI has not been tested."
