Each of the 4 valve loops (1-4) then have to be pulled out and tuned to a reasonable pitch for A=440 slotting.

The good news is that with the tuning slide in the leadpipe, you tune the horn once rather than tuning the large and small sides separately. The bad news is that the "leadpipe tuning" horns usually don't sound as nice since the cylindrical length of tubing is greater and the connical doesn't start until after the 5th valve.


Thank you.
