I think there called "warr" guitars...though war would be cooler.If those stick/tapping instruments were not so expensive,I'd get one.Dont throw out your guitars and basses just yet.I think it will be a long time before guitars are universally replaced by superior tools for expression.Digital amp modeling and other guitar/amp innovations are still in their infancy.It would be like another format of video coming out after everyone just got done accepting the dvd format as a valid change from vhs.
Later! \m/
