Thomas Michael Caldwell (November 9, 1949 – April 28, 1980) was the bassist for The Marshall Tucker Band between 1973 and 1980.
Caldwell was known for playing a white 1970s Fender Precision Bass with a Dimarzio Split Coil Pickup.
A mix of finger style and picked bass as well as his use of tube amplifiers contributed to Caldwell's signature sound.
A native of Spartanburg, South Carolina, he died at the age of 30 from injuries suffered when his Land Cruiser clipped a parked 1965 Ford Galaxie on April 28, 1980.
Another brother, Tim Caldwell, also died in a traffic accident one month before Tommy, on March 28, 1980, at age 25.
