I had the Upton crew put one of these C-extensions on a Hawkes Hybrid. I received it a couple of weeks ago and have been testing it ever since. And, I must say that great care was taken in the design and implementation of this extension and bass. The extension produces a strong and solid low end. It is a very impressive C-Extension. Although, I might suggest that a thin layer of some type of isolation (perhaps rubber) be placed between the wood of the extension and the scroll to reduce rattles. But, overall this bass with the extension performs far and above other basses in this price range. Thanks Very Much!
COMMENT FROM UPTON BASS:
A layer of cork actually sits between the maple extension and the scroll to reduce vibrations. I believe the "rattles" you are hearing are the string oscillating on the extension. To make an extension not do this, the string heights would have to be VERY high. Enjoy your bass!
