Womack 1-row 4-stop key of D with Binci a mano reeds. This is a one-off instrument by a builder from Scarborough UK. It is built like a typical north American one row with one fixed upright reed block and two banks of reeds mounted flat. The treble buttons are ebony. It plays well, but it’s not quite as loud and bright as the boxes from well established makers and is for sale at less than half the price you would normally expect to pay for a box like this with Binci reeds. It is cajun tuned with all C# and F# notes tuned to approximately just intonation. Tremolo is based on 3Hz/14cents which is a bit wetter than typical Cajun boxes. Sold as is, but with options for different tuning or other improvements. Comes with an adapted case.
