Is it the reverse leadpipe or the back set brace

    just a random question
    I have heard the reverse leadpipe is freer blowing but when you have a reverse leadpipe the bell brace is set back closer to the valve block. I think that the brace might actually have more effect on how the horn feels.
    Your thoughts?

    It is the brace. The inside taper of the leadpipe would affect the feel also. The reverse leadpipe has a minimal effect on the actual response of the horn in my opinion.

    I think the same. The reverse leadpipe gives the horn very little resistance, since they put the brace farther back it allows the bell to ring therefor giving a different sound.

    I think the brace placement has more to do with it than the reversed tube. I used to have a 1950's Olds Ambassador that I used for big band. Among other things, I had the last bell brace removed, and it really opened the horn up.

    It is science, not opinion. It is not freer blowing, the player simply hears themselves better because the bell is braced further back.

    Rowuk, I respect your opinion a lot, I am not trying to prove you wrong.

    I think that reversed leadpipes are freer blowing because they have less resistance. The brace also plays a big role in the sound.
    The reversed leadpipe stats from the Bach Loyalist reads:

    The 25LR leadpipe: Reversed construction, longer form of 25 with less resistance. Because it's reversed, its overall longer. Is is said to give little resistance, but alot players hate LR pipes.
    the 43LR leadpipe: Reversed construction, longer form of 43 with less resistance. Like the 25 LR but has even less resistance.

    After reading these comments, I think I'll start designing " accoustic brace dampeners " . Nahhhh...forgive me....I'll just stick to the lottery.

    Cody believe ANYTHING that you want. If you need to believe ad copy, do it. I have tested all of this stuff and discovered first hand what I post.

    My research shows the resistance argument as pure BS. The pressure resistance is determined by the smallest diameter - which is found at the mouthpiece (or even better, the aperature for strong players). The AC resistance is in fact determined by the "leakage" in the resonant system, which is at the bell. What the player "feels" is mostly what they hear. I have proven this many times over by simply giving the players earplugs and gloves so they do not "hear" or "feel" the horn. Then they discover that there is little to no difference in the reverse/standard comparison.

    Robin,
    Does the set back bell brace"loosen up" the horn? My verbage for getting more sizzle.

    I find that the reversed setup "distorts" earlier. Depending on the specific bell/leadpipe/material, that could be more sizzle.
