Trumpet Trim Kit for improving the sound. For all Bach Stradivarius Trumpet. Custom made KGUBrass (MEDIUM, Antique Bronze Lacquer)

Overall nice trim kit, BUT- Have a Bach Stradivarius Model 37 and both the bottom and top valve caps fit fine. But 1 of the 3 finger buttons wouldn't thread onto any of the 3 valve stems. Also some of the buttons didn't screw all the way down. Had to order another kit and to get a shot at getting the 3rd finger button to thread. Was able to find one, but it seems that the machining tolerances of the finger buttons isn't to very exacting standards because it took two kits to get the finger caps to thread to the valve stems. Somewhat disappointing as will have to return one of the kit. Amazon did ship the replacement kit free of charge.

I played professional trumpet for 30 years and the focus for slots and deeper harmonicTones in lower register are amazing. Makes my Bach Stradivarius much heavier. If playing lead trumpet and want a brighter sound than use this for orchestra work. Also bought the mouthpiece booster from KGU Brass, and it really does help the focus. Only negative , is brass will tarnish. So get some Brasso to polish the brass .

Me encanto el producto, caí perfecto en la trompeta. Y el sonido que sale es bien agradable, arregla mucho la vibración de la trompeta..

Super easy slotting, pure clean tone production, a true enhancement for any professional trumpeter or beginner.

Pretty decent valve kit. Came in quickly and does warm and darken tone. It should be noted that the raw brass valves will begin tarnish based off where you place your fingers on the horn. Overall a solid product.

Excellent!

Good

Bought this trim kit for my Bach 183 Flugelhorn. Looks great, fits perfect and adds just the amount of mass I was looking for. Thanks Comrades at KGU Brass.
