This is a heavy-weight reed for the more experienced user or the person that tends to be heavy on tongue pressure moving big air volumes. The main black latex reed is .003 thick that punches up good top end range bugles that carries in big open country. We paired it with a heavy .004 piece of latex on the short side combined for a total thickness of .007. This thing is a durable double reed and can take a lot of use and abuse. A true guide/outfitter work-horse elk reed that is still very nimble to run but retains tones and gutteral thump when you want it.
NOTE: As with all stacked reeds there will be a short break-in period. Crank 20 bugles on it, set it aside and let it dry, and it'll be good to go.
