Good friend and luthier Gary Upton has finally begun offering a C extension over at Upton Bass. These extensions are different from ones I’ve seen in the past, and look like they might be a compelling option. Gary described to me that the piece is made
out of english sycamore (what americans call maple) and best grade ebony. He also states that he plans to create a
very lightweight version that is just sycamore and no ebony cap.
One thing I can see from the photos is that the conduit for the string manages to avoid drilling a hole through the scroll. That’s a nice feature. The unit appears to do a good job of having a minimal impact on your scroll.
A few years ago I helped Gary develop and design the current state of uptonbass.com, and I’m glad to see it has expanded greatly. I am very excited to see a venture into the low C world for this shop. Maybe I’ll have to send my bass out there for an upgrade!
