Are you wanting to increase gain or just make it louder?
Also, how flexible of a boost do you want?
There are some boosts that give you EQ flexibility - the Xotic RC Booster or the Voodoo Lab Giggity.
There are others, like the Xotic EP Booster, that are just a single knob and pretty much the eq is set.
Also, the way you run it will make a difference - for instance, boost into OD will make the OD dirtier and gainier - boost after will take the OD sound and just make it louder.
