It’s too bad they couldn’t come up with different levers. But if you tune in C, wouldn’t that cause more stress on the E’s & B’s to begin with? Grant it this solution eliminates the need to flip the levers, but if you want to play in the key of F you’ll be stuck. Hate to see you sacrifice key versatility- I would wait to see what the technician says if it were me.
Was the Ogden new as well?
