I was wondering what is the purpose of the charge pump in the BaconBits pedal. I own a BBE Boosta Grande opamp booster and it doesn't have a charge pump. Can the BaconBits be built wihout one?

No, the charge pump is used to supply -9V to the opamp. The design could be modified somewhat by way of biasing the signal, but that would significantly change the circuit.
