[quote name='cris the man' post='105724' date='Dec 18 2007, 08:20 AM']then theres the issue of being a fussy bass player , not wanting to use a pic , is it possible to sweep pick using a relative fingering technique?[/quote]
Don't see why not - if I understand the technique correctly, the key is the other (fretting) hand, the muting and unmuting of the right strings at the right time. If you get good enough at it, you might be able to produce notes so short, you can't tell what note it is.
