Hello I am Jacky! New member here!
Is there anyone knows there are other servo that compatible with SSC-32 Servo Contoller beside these 2 servo (HSR-5980 or HSR-5990)?
Mind to share with me?
Thank You!

The answer is all R/C type servos work with the SSC-32. Futaba, Towerpro, etc… Having said that, some servos may operate backwards so when you expect it to rotate right, it will rotate left. It depends on the internal controller board inside the servo case.
Standard servos as well as digital servos both work with the SSC-32 the difference again lies with the internal controller board. Digital servos have higher resolution and are more powerful due to the resolution.
So there you have it in a nut shell… 
What about the Hitec Servo?
izi’t all compatible with SSC-32?
Thank!

Like SN96 said, yes all RC (pwm driven) servos will work. And especially the Hitec servos 
If you’re not on a tight budget, I would seriously stay away from the Towerpro servos… It’s not that it won’t work, they’re pretty lousy in terms of reliability and precision…
You mentioned the 5980s and the 5990s, so I’m guessing that you’re not on a tight budget.
I would seriously consider the 5990s. They are truly awesome servos. Watch your fingers though, they are STRONG…
