What’s going on with this? Looks like a closed wrap… as in a wrap that doesn’t have an entrance and and exit port??

It’s a spare tuning slide for when you jettison your F-attachment tuning slide over the heads of the percussion section. Just grab the spare, insert and go! Hey, if the drummers can grab a new drum stick and keep playing, we should be able to do the same.

True to their cataloging system, Yamaha plans to produce a 600 series model (professional) with spare main and F-attachment tuning slides. The 800 series model (custom) will also include a spare outer hand slide…..they haven’t decided where they are going to store it on the horn yet.

Fairly sure that's a built-in F valve extension. Remove the slide from the additional wrap, and then the two slides connect to the additional loop to bring your valve to what looks like Eb.

Looks like you may have to remove the main tuning slide to put the slides into the extension, which complicates things a little. Cool idea, though.

What the? And it looks like that second blind tuning slide is made so that it's the OUTER that pulls off. All I can think of is that maybe it was different previously, and allowed an attachment tuning in Eb?

It's a custom job, this is not a stock instrument.

Custom job, but done very well. And Yamaha actually has a history of doing extension loops like that from the factory (on the YMP-201 circular mellophone), so it's almost plausible.

I thought the same thing about being an Eb optional or something but wouldn’t that require one more tuning crook than pictured? I’m creative but not THAT creative

To use it as an extension, you'd pull both slides and then insert them behind the tuning slide, 90 degrees off from their original orientation (like a Schagerl Aurora bass). The long tubes of the wrap form a square so you can do this.

Yeah that looks like it would work, except that one crook is ONLY female and the other crook is ONLY male. If you turn 90⁰, it wouldn't work.

That would only work if the tubes soldered on to the horn are a smaller bore than the rest of the wrap. They are functioning as inners, so the outer on that extra slide would have to fit inside the outer on the original slide, and vice versa. I think it's gonna play pretty stuffy.

You're right, I didn't look that closely... seems silly to build it that way. I liked my way more!

Yeah, they probably didn't have the right tubes so they just used whatever was lying around, I guess.

Think more in the spirit of the MTS art... tubular counterweight/stash compartment; balance adjustable via the number of Slim Jims stored inside

Hmm wonder if edwards ever considered a slim Jim harmonic pillar
