    This may be an elementary question, but I need the info. My I bought a while ago came with heave and lighter caps. All I've ever heard is that the weights are used to put pressure on different parts of the lip.... is this all there is to it or are there and other direct effects on the tone/feel etc.
    Thanks

    It is not about pressure on the lips. Adding mass or taking it away from a horn changes the way it sounds. In general, the lighter the horn, the brighter the sound, and the heavier, the more dark the sound gets. it can also affect the projection and slotting of notes.

    A horn designed light is optimal with the caps it came with. It is possible to pimp the horn with heavier weights, but there is ALWAYS a tradeoff. Most often, heavy weights on a light horn improve the slotting, but emphasize intonation problems.
    The power of suggestion drives the sales of these things with claims that are not backed up by any physics.
