Tremoverb channel cloning not working?

[aselix68]

I've got late 90s tremoverb head...I set the channel cloning to "red to vintage" and it doesn't change anything. Maybe I'm doing something wrong? Any other settings to make this work, or do I have an issue?

Thanks!

I recently picked up a tremoverb and have the same issue. Orange to Red works though. How about for you?
