I just been trying a Kurun & Gilbert T6B, and I'm getting a metallic taste after five minutes of playing. Has anyone else had a similar experience with them? Bought from Thomann.de.

I'm using it on a small horn, and it has a wider rim and larger throat that seems to work for me.

The metallic taste has gone now, must have been oxidation after not being used for over a year.
