Along with his bass duties in Sadus, he also plays keyboards.

Di Giorgio has been married for years, and is the father of a daughter who was born in April 1994.

The family currently resides in Oakland, California.

Di Giorgio endorses Ibanez Guitars and primarily plays a number of different fretted and fretless BTB basses.

He previously played two custom Mjolnir basses by Thor Bass; a custom made 5-string fretless model which he has converted to a 3-string and a custom-built 6 string fretless.

He's also played custom ESP basses, mostly a F-series fretless 5-string bass in a dark green finish, but also uses a very unusual double-neck construction with a fretted and a fretless neck in one body.

He currently uses an EBS Fafner head as his main sound, but has also used Ampeg and Randall in the past.

In October 2019, he founded the fusion-world-metal group Quadvium with fellow fretless bass player Jeroen Paul Thesseling.

A year later, he formed the death metal supergroup Act of Denial.

Within his genre, Di Giorgio is respected for his highly technical playing skills.

He is also credited with being the first bassist to bring fretless bass playing into the heavy/extreme metal genre, and often plays bass by using his fingers, although he has been seen using a pick on certain songs.

Di Giorgio has stated that his main influences as a bassist are Geddy Lee, Chris Squire, Geezer Butler, Steve Harris, Stanley Clarke, Jaco Pastorius, Billy Sheehan, Dave Pegg and Charles Meeks.
