Miraphone TU25 Rose Orchestra - A Forgotten Mouthpiece?
Posted: Sat Nov 28, 2020 9:22 pm
Recently I got a good deal on a Miraphone TU25 Rose Orchestra mouthpiece. Being down for the season, I have been experimenting with mix-and-match on mouthpieces on my Bessophone and my 183. Next, I will be dragging out the souzy from the back of the closet. Since I like mouthpieces with @ 1.28-9 inches / 32.5-7 mm i.d. cup diameter with moderate throats and backbores, I tried it. I am pleasantly surprised. With its extra deep cup, It has a really smooth tone with good response and ease of transition through slurs and registers. I feel it as part of the horn, not something to have to blow through to get to the horn, as is the case with so many mouthpieces. On my Bessophone, viewtopic.php?f=4&t=144 , with the cup so deep, the dreaded "flat fifth partials" are tending to make their appearance, unlike when playing with my shallower mouthpieces. But only mid-line D seems to need the alternate fingering, and then not all the time. Near pedals all the way down to true pedal BBb are smoother and speak better with the usual "riding throttle" on the first valve slide to keep intonation down where it needs to be. The TU25 has a very smooth tone, probably due to it having a similar depth cup to a Wick 1, but unlike the Wick 1, the TU25 retains core, where the Wick 1 can get diffuse on this tuba, although the Wick 1 is probably the best mouthpiece designed for the inherent stuffiness of a Besson BBb comp. The good thing is that the TU25 doesn't take a third lung to manage air on this tuba, as does the larger throat and backbore of the Wick 1.
Right now, except for the mid-line D, I don't notice anything awry or unmanageable with intonation otherwise; again, time will tell when we all get back up and running, supporting ensembles, tuning with a section.
I can see why it may have fallen out of favor: the cup is really deep. It lends a darker character to my Bessophone compared to shallower mouthpieces, including, for example, a Bach 18, which of course is a brighter mouthpiece, and my blokepiece Imperial with the 32.6 modified Helleberg rim and a half-thickness spacer. Right now, I don't have a Conn Helleberg 120S to compare it to, but again, from memory, the TU25 has a little more fundamental in the tone than the 120S, even though it feels like there is a little bit more curve at the bottom of the cup into the throat than the 120S. Doug Elliott's chart lists the TU25 as an "S" depth, deeper than a Wick 1, and deeper than any other mouthpieces on the chart or what he makes. I'm not sure it is that deep, although the depth does feel like it could be similar to the old King 26, although it has been so long since I played a King 26, The King 26 could be even deeper. The TU25 actually feels maybe only a hair deeper than a 24AW. That may be due to the difference in respective cup diameters. But even after all that, it is still surprising that as deep as the TU25 is, unlike a lot of other deep mouthpieces, it doesn't suck the air out of a player.
I see having both the TU25 and the blokepiece at the ready: the TU25 when there are others in section, and I want to provide a good foundational tone; the blokepiece when I need a little more definition and projection.
The rim is a little wider than I am used to, but very comfortable. I think I can get used to it very well. Centered on my embouchure, the edge of the rim is still below my nose as I prefer for comfort and flexibility. Deriving the math from the specs given, the rim is 8.35 mm, and it has a comfortable crown.
The shank on my example measures right at the "American" .520, seating very well in the old receiver of my Bessophone. The bore is the 8.2 mm / .323 inches / "P" drill bit, which is the same as what bloke prefers. The throat feels like it has a moderate taper to it, neither too tight nor too open barrel. I believe this contributes to a moderate slotting: not so tight I have to be riding slides all the time, but not so loose that centering articulation becomes an issue. The actual cup shape of the TU25 is reminiscent of, but again, probably a little deeper than, the Curry 128D I used to have, but sold when I changed the bell on my Bessophone from the detachable, as at the time I had nothing that I could optimize with it. I don't see the TU25 being quite as versatile as Curry describes his D cup, which from my experience it was very versatile indeed. I say this even though the 128D was my only mouthpiece for several years; it performed well in all settings with the former detachable bell.
I won't know how the TU25 will function in concert for quite some time, as the community bands I play in are both shut down for the duration of the virus. But one day we will all be back up and running with our respective ensembles. I will report back then. And in the meantime it also actually gives better fundamental to the tone of my old Eb 183, without any apparent warping of intonation. I will know more when I have a servicing done on the 183: rotor alignment, bumpers, receiver angle, check for leaks, etc. Even though I have not tried it on a souzy yet, I surmize that the TU25 may not be a good outdoor mouthpiece for a souzy, where projection means everything, but could tame a souzy for indoor use in a situation needing to get tuba support past really bad acoustics. For that, I use my Jim New custom 18 he made for me when he was still with Zig Kanstul, with a 1.28 cup diameter, deeper cup than a Bach 18, and a hair larger throat at .328.

All in all, for me the TU25 is a good mouthpiece to add to the arsenal. As usual, these are my observations. YMMV. Thanks.
