Engelbert Schmid is offering a new option, nickel-free components. For people with allergies to nickel, playing the horn can present problems, form rashes to blisters to illness. Now you can order your Schmid with nickel-free levers, hand guards, and mouthpipe parts (guard, ferrule). This is usually enough to prevent nickel allergies. If that doesn’t do it, Schmid also has the capacity to build a completely nickel-free instrument. Here’s a link to a page about Schmid’s nickel-free horn.
