In Reply to: How much does it cost to turn a 3 valve tuba into a 4 valve? posted by Jerry on March 03, 1999 at 23:37:52:
I have added 4th valves to several instruments. All of them have been front action tubas. Much of the cost and hassle depends on the availablity of parts and the configuration of the tuba. I suggest that you e-mail me directly with more details of your tuba. We could discuss your options then.
