dnsacks, yes, I've already ground down the case, thanks though! I've had many nice recordings, but I hooked it up to catch my wife playing the piano, and it sounded horrible. Messing with the opti cable seemed to change how much popping was in the recording.
John, I can snag a brand new one for just a couple bucks more from partsexpress.com (unless I'm mistaken and yours is new).
