Melvin George Schacher (born April 8, 1951[1][2]) is an American musician who is the bassist and a founding member of the hard rock band Grand Funk Railroad.

At sixteen, Schacher caught his first professional break when he was invited to replace bassist Frank Lugo in Question Mark and the Mysterians, and he supported their hit "96 Tears" (1966) on their 1967 tour.

Intrigued by the power trio concept, Schacher joined the new lineup, and almost from the moment they played the 1969 Atlanta International Pop Festival, inspiring a rousing reception and fast-spreading word of mouth, they achieved international fame as Grand Funk Railroad.

Schacher spent the intervening years making his way as an investor and occasional musician until, almost by chance, he reteamed with Farner and Brewer in a reunited Grand Funk Railroad in 1996.

Schacher and Brewer enlisted veteran musicians Max Carl (38 Special), Bruce Kulick (Kiss) and Tim Cashion (Bob Seger, Robert Palmer) and have continued touring as Grand Funk Railroad from 2000 to 2012 performing 40 shows a year to large audiences all across North America.
