I was hoping someone could identify the kind of Bart soapbars my bass has so I wouldn't have to take the strings off and unscrew the pickups-I'm looking to order another pair for my other bass. They measure about 4 1/4 in. long x 1 1/4 tall, and have one screw on either side. Here's a pic if that helps. I couldn't find a matching set on the Bartolini website (which is pretty out of date). Thanks in advance.
