Very rare! Bach Stradivarius 19072X in factory raw brass. One of the new creations from the mind of Andy Lott and Bach Brass. This is a 72 bell horn that uses the weight from the Mt Vernon era with an updated valve block that pays homage to the NY and Mt Vernon designs of the past. The 43 leadpipe is nice and open but still offers friendly resistance. The leadpipe is also in gold brass that helps round out the sound. The horn can sound bright and edgy with a lead style mouthpiece or nice and smooth with more of a traditional cup. These horns are very special and very rare right now. Other design queues include nickel inner slides, a unique tuning slide, nickel braces, and a water key on the 3rd slide with a stop screw. Horn has an ML bore. Valve and slide action is like new and the horn has a valve alignment. No damage or any past repairs. One minor ding on the side of the bell. Horn has also been tweaked and adjusted by Andy. Serial is 801XXX. New these horns are over $4400 if you can find one!
