American unfixed cut, lively response for a free sound. The Forestone material is a mixture of polypropylene resin and cellulose wood fibre. More than 50 percent of the wood fibre used is Hinoki wood. The material is brownish in colour, tasteless, odourless and non-toxic. The exceptional sound, resilience and flexibility of Forestone reeds is due mainly to this special material. Forestone reeds are made by proprietary injection moulding developed in Japan. This results in reeds with optimally smooth vamps that are exceptional uniform and consistent, reed to reed. Forestone reeds are perfectly balanced side to side and front to back. The more or less standard profile tapers down to 0.1 mm thickness across the tip. Held up to the light, the reeds display the classic upside-down "U-shape" associated with cane reeds. Forestone reeds tend to maintain their strength / resistance over time. They vibrate well and hold the centre of the sound in a manner similar to that of a good quality cane reed. The basic timbre is robust, clear and strong, with just enough "buzz" to ensure projection and carrying power. Intonation is stable and the reeds articulate well throughout the range of the clarinet and saxophone.,,Feel,The difference in feel between Forestone and cane is minimal. That said, it is the wise player who takes some time to get comfortable with Forestone, in the same way as he or she would take time to get comfortable with a new mouthpiece, ligature, barrel or instrument. Blowing resistance can be adjusted with Forestone reeds by slightly raising or lowering the reed on the mouthpiece table (slightly lower placement = slightly less resistance, slightly higher placement = slightly more resistance). Although other types of adjustment are usually not necessary, the material is sufficient hard that one can still do so using blades, files, sandpaper, reed rush or whatever other tool or implement is desired. One can also clip Forestone reeds successfully. The useful life of a Forestone reed will vary from player to player given that everyone's way of playing - his or her embouchure address - stresses the reed differently. Forestone reeds will far outlast good quality cane as the proprietary composite material is impervious to water-logging and breakdown by saliva, and will not warp due to changes in humidity or altitude. After a certain number of hours, however, the reeds will begin to feel less lively and responsive. The loss in vitality, be it subtle or more pronounced, would signal the time has come to retire the reed in favour of a newer one.
