Ive heard loads of people say stuff about hotrodding their bass. but...what does this actually mean? I know a guy with a "American hotrod P bass" and it has a J pickup at the bridge. and on Mike Dirnt's signature P bass the pickups are "hotrodded". Is it just an american word, for modification? oh btw just for fun i looked it up on urban dictionary, and heres what i got http://www.urbandictionary.com/define.php?term=hotrod so im assuming its something similar to the first definition right? improving performance?
