The instrument was made by Sterling when they had a development initiative with Concerto Instruments. The Euphonium was developed promoted and played by Steve Mead. I was lucky to get my hands on one as I did some evaluations and promotions myself and played it regularly for many years in top UK Championship bands. I am playing more Tuba these days so its surplus. It's a lovely compact sound, with great projection IMO - NOT a huge ‘wollowy’ sound and I think intonation much better than Early Sovs. It's more like a modern version of the older compact Imperial or similar to the rarer Medium bore lighter Prestige or even rarer German Miraphone Euphs. It has a soft red-brass bell which also makes sound very warm. It doesn't have triggers but doesn't need it. I played it on a Bach 4G, hence the comment about doubling for pro Trom player.
