I don't know how many of you guys have seen the guitar solo for "Testify" by Rage Against the Machine; but what Tom does is take out his cord and touch his pickups (making that crazy feedback sound) and moves his wah. It makes a really cool sound. I've decided to try it on my bass. I just unplug the cord a little bit (still in the jack, just not in all the way) and move the wah, and I can get some awesome sounds. Should I not do this a lot? Will it damage my bass, cord, amp, and/or pedalboard? Thanks!
