A VALVELESS F-ATTACHMENT TROMBONE!!??

[BGuttman]

We discussed this before (I just can't find the topic).

Here is the old topic...

rotorless F attachment. You read that right

It seems to me it is still a valve, however.

It's shifting pipes. I guess it's no different in function than a Vienna Valve, but the "valveless" claim is because there is no rotor, piston, Axial, Hagmann, K, Miller, erc.

It is a solution in search of a problem!

Those unable to remember that past...

Reference Shaw's disc valve, which by contemporary accounts was afflicted with significant leakage trouble.

This guy has posted videos of his own valve without the annoying computer voice. I think he called it "rotorless", not "valveless". It obviously is a valve. Just a unique type. And yes, it is similar to the concept of the disc valve.

I disagree. The holy grail of trombone is a valve that plays exactly like a straight horn plays. I think it's quite ingenious. Would love to try it.

Whoaaaa, did you discovered this??!?

LoL, robot voice comment. Yet another video with almost no original content, just ripped videos from other people's pages, posted on an ad enabled channel.
