We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal to superluminal. The model is an extended {lambda}-type system with two extra control fields and an extra energy level. Phase variation of one of the control fields imparts the tunability in the group velocity along with other interesting spectral behavior in the absorption spectrum.
