Matt, my Getzen came with two extenders for the 5th valve. Normally, of course, the valve is a flat half-step, and then the extender I use makes it a flat whole step. However, there is another extender that is slightly shorter that makes the fifth valve a whole step. This makes the 5th valve equivalent to the 1st valve, and is the BBb conversion. Then, all you do is pull the other valve slides slightly and everything should line up. It basically creates a piston tuba with a leadpipe slightly longer than a rotary valve horn. That's why I don't really buy the argument that the sound quality suffers.

If you combine all the slide extenders, you get the equivalent of the older Mirafone fifth valve setup (2+3)
