Benefits of reversed tuning slide on Bach 50

[bassboneman69]

Hello forum friends,

I mostly play an Edwards 454.
The main tuning slides on these have the reversed tuning slide legs…
If one were to replicate this on a Bach 50 what are the expected performance benefits or conversely the detriments to doing so?
Thanks all…

That depends entirely on the parts that are being used. Is the gooseneck also being considered in the process?

Hi Matt,

I am not sure.
May I please PM you about this?

I know Matthew will give you all the information on this, but you should know there are much more significant differences between the Bach 50 tuning slide and an Edwards tuning slide than just the reversed first leg of the Edwards. In short, the Edwards tuning slide is much larger in every dimension.

FWIW, when I first had my T-slide reversed, I had the same gooseneck. Later, after exchanging the valves, my tech installed a different gooseneck. More even response throughout, which is important for a Bach.

Hello gents!

Thank you for this information.
Is the gooseneck a different make than Bach?
Or can the present gooseneck modified?

In my case, with the first set of valves (Kanstul CR valves), the gooseneck was the same, just modified slightly—I believe it was shortened to bring the instrument in tune. It worked fairly well.

Later, when I asked a different tech to install a set of Instrument Innovations rotary valves, the tech installed a different gooseneck. I don’t know whether it was available as a ready-made part or whether it was custom made for my horn. The tech also installed a different first leg for the tuning slide (the inner or “male” portion of the first leg). The two together appear to make a longer gooseneck—the transition from the gooseneck into the inner slide appears to be one continuous taper.

I don’t know how those two parts are made, or where he got them.
