I know that there’s regulator reeds made of bronze , but never hear before that chanter reed can be made of brass…anybody else know about this more.
this is my bass regulator reed made by Marc v Daal

I think Colin Ross shows how these are made on one of his YouTube reedmaking videos.

Dave Hegarty talks about using pop cans for reed making, although again in the context of regulators. The reference is on page 60 of the PDF here:

I believe the best in the business have tried making uilleann pipe chanter reeds from brass, copper, phosphor bronze, yogurt tubs, beer cans, hamster water bottles, accountant’s green eye shades, toenail clippings, etc. without success. Brass reeds (and some of the aforementioned objects) seem to only work in single-octave applications such as regs. But that’s about it.

That’s how my bass drone reed looks from Marc van Daal
