Maybe call it a 'step-brother' or something. No, the SX90 is the 'little brother' to the SX90R. I've also read in a couple places that the EX90 is a 'little brother' to the SX90R.

It's not something I have had enough of a sample of to give any opinion. That's a horn that's most likely fully made and assembled by Keilwerth.' I see a lot of folks go back and forth on the quality of Amati made/assembled horns. I think the best advice on the ST90s and EX90s is, 'Look for a, 'Made in Germany,' stamp. However, I also saw some ST90 IVs with a really high serial number (420xxx) that looked more 'Keilwerthy.' I can't really prove either way if these horns are 'made' by Keilwerth and 'finished' by Amati or if Keilwerth just sent some plans to Amati and said, 'Build some horns for us.'Īs far as the ST90 is concerned, the first ST90 I looked at - no numbers after it just 'ST90' - was clearly stamped 'ROC' and didn't look very much like a Keilwerth.

So far, I've all the EX90 and EX90 IIs I've seen are stamped, 'Made in Germany.' The EX90 IIIs I've seen do look like a Keilwerth and aren't stamped anything, except for a very high serial number (320xxx).

That doesn't quite line up, even doing fast and loose research. Assembly and finishing by Amati in Czech Republic Saxpiece comes up with the following list:ĮX90 III Parts made in Germany. * Probably the first 'student model' is this, which is an obvious stencil of an Amati Classic Super. The folks on SOTW decided it's probably made by B&S. It also doesn't look very much like a Keilwerth-made horn. * The Keilwerth Student Modelle, which was also marketed as the ST (i.e., not 'ST90'). saxpiece, from Sax-on-the-Web, has done a very good job of breaking down these horns. If I had to guess, I'd say they're made by Amati.ĭiscontinued student/intermediate horns include: * The 'Julius Keilwerth Edition.' I'm not 100% sure where these horns are or were made. These horns are made in Taiwan and aren't available in the US. * The ST1100 soprano, which is probably all manufactured in Germany, but may be assembled by Amati. That being said, Keilwerth has had some interesting things in their student lines.Ĭurrent student/intermediate horns include: I've made minor exceptions for that a couple of times, but student horns kinda bore me.

First, I don't particularly care about student horns and I rarely do anything with them.
