Here we have a Bach 36G Stradivarius Straight .525 Bore Trombone - the G meaning it has a gold brass bell. Born in the mid to late 1990s - it's just a shiny young zoomer! The difference between gold, yellow and red is the copper content in the metal. Gold tends to have a warmer sound than yellow, but not quite as diffuse as a red brass bell.
This trombone arrived in really good condition, all it needed was a basic clean on the inner slides and main slides, and some minor dent work.
This listing includes the original brown zipper case, which often gets damaged or retired earlier on, but this one is next to new!
