id say go for a booster.
Im not much of an EQ pedal guy... i think the EQ from amps are more then adequate ..
if the amp is miced up.. i may fiddle with the EQ from the mixer...
im using the BBE sonic stomp as a sorta buffer to compensate for a bass heavy amp , or a trebly amp ...etc.. the lo/hi knobs help me get relatively consistent sound at different venus
if currently your guitar tone is generally too ... bassy/trebly etc.. you could re-tweak your entire setup to compensate.
