I've got an SE Soapbar II that I picked up on a trade, and it's turned out to be the best 'bang for the buck' guitar I've ever owned. I recently picked up an SE Singlecut Soapbar to go along with it. When I removed the bridge from the Singlecut, I noticed that it was considerably lighter than the bridge on the Soapbar II. I don't have a digital scale to get the exact weights, but there is definitely a difference. Could the Soapbar II possibly have a US bridge? If so, would there be such a noticeable weight difference? The Soapbar II is a 2004 and the Singlecut is a 2008. Could the older SE models have used a different material for the bridges?
