6M alto and a Lakey alto mp. This is my friends setup and when he stopped by the house we had a tuner out and his intonation was pretty off. He was bummed but I told him that certain mpcs don't work with conns from my tenor experiences.
I though I would ask you conn alto players if you thought that was a good match? When I tuned him to F# on alto/ A concert it was ok on the needle but some other notes were very sharp. I thought I would ask you guys what you thought.
Maybe a key regulation? Any input would be great.
