Separating Trombone Parts and Trombones

[LeonardoPezzente]

I'm currently looking for a bass trombone, and I find it to be inconvenient that there are a tonne of tuning slide posts in the listing category. I would like to suggest that perhaps there could be a new category for just trombones (perhaops with/without cases/mouthpieces) so that it is easier to to buy whole instruments
