@administrator said in Bach Club:
MLV is the marking Bach put on all trumpets that had a Medium-large “Vindabona” bore.
Mine only has "ML" stamped on the #2 valve casing.

From what I understand, Vindabona (dual-bore) actually only applied to the tuning slide. The rest of the trumpet is the same bore, I think. I should do some research on it. I know, I will ask ChatGPT:
The "Vindabona" bore is a design feature found on some Bach trumpets that refers to a specific type of tubing that is used in the instrument. The name "Vindabona" is a reference to the ancient Roman city of Vienna, which was known as Vindobona in Latin. The Bach Vindabona bore features a slightly larger and more gradually tapered leadpipe, which is intended to provide a more open and free-blowing feel to the instrument. This design can result in a more resonant and responsive sound, particularly in the upper register.
It's worth noting that not all Bach trumpets feature the Vindabona bore. Some models, particularly older ones, may use different bore designs or may not have a specific name or label for the bore. Additionally, while the Vindabona bore can have an impact on the overall sound and feel of the instrument, there are many other factors that can also affect the trumpet's tone and playability, such as the mouthpiece, valve design, and construction materials.
I cannot guarantee if that is true, but that's what ChatGPT told me.
