Handmade by Fred Lamberson in California.
L Series: "This is my traditional jazz mouthpiece. The bore and baffle are a copy of a 1950's metal Link that Pharoh Sanders gave me. It has evolved somewhat over the years, but is still as close as I get to the old Link sound."
J Series: "This is an L modified to have almost no baffle, it is my darkest piece. I say darkest because it has the least amount of baffle, but I have heard from enough players who say the sound is so huge that they don't need a baffle. I think the freedom of not blowing against a baffle allows the sound to emerge without the bright edge a baffle makes."
