The W-A1 is based on the vintage Wheatstone linota anglo. Both instruments share the same reed pan layout and construction. The A-1 is available with vintage type parallel reeds (standard), or the Wakker tapered reeds (optional).
The Wakker reeds option consists of long scale tapered reeds, with better reed scaling (more reed frame sizes for the same compass) which results in a more powerful tone and better balance.
The standard A1 configuration has hardwood flat ends, raised or metal ends are optional.
