acid producers --- distortion pedals?

[j_s]

I have the FB383 freebass which tbh it a pretty weak sound.
could i get a fatter and more screamy sound if i used a distortion
pedal or something with it?

what pedals are recomended..

what about the Boss DS2 or Boss OS2 ? whats the diff?

what bout the "Marshall Guv'Nor Plus GV2"
any suggestions?

think the overdrive (OS2) is more subtle than the distortion. thats what the terms usually imply anyway.......
