The Gonzalez RC Alto saxophone reeds have a classic, French style filing. These reeds are made on a segment of 3.6mm. Rectified to 3.2 mm. this leaves the scraping in the most vibrant area of the reed and produces a very brilliant sound.

The material is stored to age for at least 2 years before its manufacture.

Its shallow shoulders have a closed half-moon shape. This helps to maintain the tuning despite being an extremely flexible and spontaneous cane.
