Are you getting a bad ground hum from your RS pickup? I have tried 4 different RadioShack connectors to go from the RCA to 1/4" and I am getting the same result with all of them...HUMMMMMMMMMMMM....but once I touch the RCA coming from the RS1 it stops. Are you having this problem? How did you stop it? What are you using to go RCA to 1/4" ??? I have a gig tomorrow so I'd really like to get this worked out. Thanks!
