Upton Double Bass Extensions

If you’re on Instagram, check out our luthier Jack Hanlon’s page: @jackhanlonbass – Jack keeps it updated with some of the many exquisite double bass C-Extensions that come off his bench!

The Upton Bass C-Extension was conceived and designed to have no structural impact to your scroll. No cuts, no notches, no drill holes. Our low pitch extensions stay securely in place entirely through string pressure and meticulous fitting to the scroll’s contours. We also refined it to be actually comfortable and playable, knowing they often are employed in rigorous playing situations.

Whether a new build or your favorite vintage instrument, Jack can carve an extension to your preferences – all while keeping the drill and saw far from your scroll!
