Who has put together a bass rig based on just components; i.e. somebody's amplifier i.e Crown, (or any body else, I only used Crown so I don;t know the names of any other brands), with a pre-amp either generic or high end, as opposed to just an amp head; regardless of the brand, which there are many, many good ones. The reason I ask is that I came across a couple of musicians who where 25 to 30 years old who were amazed that that I could put this type of rig together. Is the component rig a '70/'80's thing? No diss to the younger gents; just a curious question.
