Hidersine 6C deluxe rosin is a premium Dark rosin, a little softer with more grip than its harder, lighter-coloured siblings: 1C, 3C and 12C. Played by many a pro cellist, Hidersine 6C deluxe strikes a fantastic balance between grip and subtlety of expression. At its core, the rosin offers superb levels of grip (Grip Profile Rating: GPR#6) and good levels of attack, with the slightly softer consistency allowing a little more subtle articulation. Based on perhaps one of Francis Hiders most respected historic Cello recipes, 6C rosin is genuinely pleasurable to play, and offers you a genuinely different tonal choice too. This Hidersine Rosin is made in England in the same way as always: An Artisanal process of hand-mixing and hand-pouring. Specifications: Instrument: Cello Type: Dark / Soft Suitable for: Advanced Players. Grade 6+ Sound Characteristic: Warm and Articulate Grip Profile Rating (1: Low Grip/ 10: High Grip): GPR #6 Temperature Profile: Temperate to Colder Clima
