Guitar Serial Number: Sx

If you email Rondo Music with your serial number and clear photos, Kurt (the owner) has been known to provide surprisingly accurate information, even for older models. It’s worth a try. Have an SX serial number that doesn’t match these patterns? Share it in the comments of forums like TalkBass or Ultimate Guitar—the SX community is small but very knowledgeable.
