I just got the horn today, and decide to write this review hoping it would be useful, since no one seems to have written (or maybe even purchased) it, and it does seems to be a nice horn despite rarity.
Background
I like the response/feel of rotary valve (from my trombone experience), and have long wanted a rotary-valved instrument in Bb. Either euphonium, bass trumpet, baritone or tenor horn suits me. If anyone remember, I once post a thread asking about the Wessex Kaiserbariton, but did not get much information. Once I got my bonus this year, I hesitated between the Kaiserbariton, Wessex rotary bass trumpet, Schiller 4-valve basstrumpet, and this German tenor horn. At last I chose this horn, since the Kaiserbariton (No.2 on my wish list) is much more expensive and only have silver-plated in stock (which is also more expensive and not my taste), I don't like the look of the Wessex bass trumpet, and the Schiller is even more expensive than the Kaiserbariton.
I ordered it on Tuesday night (UTC+7), and it arrived around Friday noon. However I changed the delivery address, hence one day delay.
Fit and Finish
To be honest, I didn't expect that much. However, the finish is very good, with minor lacquer blemish on the bottom bow. Wessex engraved dragon valve caps and levers look beautiful, but I would be more happy if it has tuning slides guard rings (the Kaiserbariton has it). Fit is not perfect, and I have to use a little force to insert the second valve slide and main tuning slide, the latter of which is problematic, since the water key seems to be unable to drain anything and I have to remove the slide entirely to pour the condensation out. And man this horn fills up quick!
Tuning slides' movement is also a bit rough and scratchy, maybe because it is nickel silver in and out. And I found black residue on the valve hubs when I unscrewed the caps. However, after oiling and greasing, the movement of the tuning slide becomes more acceptable, albeit still rougher than my bass trombone (a Yamaha). The valves are also smooth if not a bit on the heavy side.
There are two strap rings soldered to the bell. No strap is included, but I am thinking about buying a saxophone strap for it soon.
How it plays
Darker than I expected. Recently I have watched many tenor horn videos (as a preparation) and in some, like this one Ernst Hutter & Die Egerländer Musikanten - Romanze für Tenorhorn 2010, the sound seems to be bright with abundant higher overtones. My horn, on the contrary, sounds to me more like a euphonium. Maybe it is because I used a large deep mouthpiece (Yamaha 51D I bought in expectation of a bass trumpet), maybe it is because the gold brass bell, or maybe it is just my perception, since my former band teacher (I play and help teach at my former school) said it sounds like baritone and not euphonium like I heard.
Intonation is not great. I have heard the baritone, euphonium, and similar instruments is inherently out of tune. However, this horn seems to be more out of tune than euphoniums I have played (and those are in quite bad shape already!). Almost an hour passed before I found a tuning slides position that is acceptably in tune, but some notes are still out of tune and require lipping, something a man who mainly plays trombone is not familiar with. However, at the end of the day I played reasonably well... I think. Some savings from now and I might get a tuning trigger on the main slide made for it. The high range (C and upper) are quite in tune, however, and high G with 2nd valve is in tune.
One of the thing I like about the horn is it has a usable false low Eb, therefore the range is fully chromatic to pedal E despite it having only 3 valves.
The horn feels quite stuffy, though, something one would expect coming from 14.30mm bore of a bass trombone to 13.00mm of this horn.
Accessories
The "lightweight foambody case" stated in Wessex website turned out not that lightweight. Well maybe it is not that heavy either, but it is definitely thicker than necessary. But for me who don't think I will have to move that thing around very much, this is totally OK. It also seems to be protective enough. However, there is only a tiny accessory storage compartment in the interior, apart from a mouthpiece slot. I can only fit a cheesecloth in it, and that's that.
I also bought a euphonium/tuba stand together with the horn, since it cannot be placed bell-down on the ground like regular euphonium. Lucky me, since the horn seems unable to be left on the ground at any position without potentially damage the valve lever rack, or rocking back and forth and risking impact damage. The stand does not fit the horn (it is made for normal euphonium and tuba), but my horn sits well enough.
No mouthpiece included.
Verdict
For $650 (+$50 for stand, $100 for shipping, and approx. $140 import tax and VAT), I am satisfied with this horn. It is not perfect, but it certainly worth the money. I don't know about its longevity and I have to find out in the near future. But as of now, I would recommend this to one who is interested in German Blasmusik, or just wants a rotary baritone.
