I've heard that since Justin Chancellor plays with a pick, Tool cannot be played on bass without a pick AND sound good. I beg to differ... I play fingerstyle and even pop/slap on some Tool songs, and it sounds alright. However, there are cases where pick-playing is the best option. Examples... Stinkfist - fingerstyle Vicarious - fingerstyle/pop 'n' slap Jambi - fingerstyle/pop 'n' slap Forty-Six & 2 - pick Schism - pick Hush - pop/slap Sober - pick If anyone else has any soundbytes or videos of themselves playing Tool without a pick, please share!
