I've recently received a Sovereign 983 EEb tuba and love the front action valves, ans so do a couple of people in my band too. Our musical director has reservations about Front Action valves, as there would be more friction and would wear out quicker.
To be quite honest, i've checked out my valves and it doesn't seem that there would be too much extra friction than upright valves. Can anyone give their experiences about wear and tear, life span etc. between upright and front action valves please?
