well i have been trying to get some good tones and sounds like led zeppelin and black sabbath. Well to get a tone like that, you need 5 thousand pounds worth of a bass and lots of amplifiers and that will cost another 5 grand. Amounting to a total of 10 grand. what if you could get a effects pedal to get that sound. id that possible or not. Maybe custom signature pedals like iommi overdrive and geezer butler overdrive or even a multi effects pedal with lots of them preset. is that a good idea or what?
