two things:
1> it's easy to make a coin into a pick. put the coin on a hard, flat surface, and wail on it with a hammer until it is at least pick-sized. shape it as you desire-hell, i used to sharpen mine to razor edges when i used them (i was 15, ok? drawing blood with your gear was ALWAYS cool then!)
2> i'm told that brain may did a cool chained-delay effect with 4 columns of voxes, each column being sightly delayed from the one before it. my dad is going to do this with 4 vibro champs and 3 delaying devices.
