Comparison to the Bousfield "S" Series: These new V and O series Bousfield mouthpieces, manufactured by Griego Custom Mouthpieces in the USA, are unique, differing from the Signature "S" series mouthpieces first released in 2013-14. The rim shapes, which were and are a hallmark element of the Bousfield line, remain the same. The cup diameters, cup shapes, throats and backbores have all been changed to achieve a balanced piece that works well for all types of trombones, from Thayer to conventional rotor instruments. The outside shape, though somewhat similar in appearance to the Signature line, has also been reworked to allow for better weight distribution. -the manufacturer/cdp
