    That technique is shown in the second blog that I linked to above.

    He's been here a while, but doesn't post often. It's only been a week and not everyone checks the place as religiously as others. But a year ago he mentioned he had an Antigua Winds SS4290 with two necks. So it could very well be a neck leak that sent his horn down this path. I must admit my bias in this regard, as in my view removeable soprano necks are just begging for leaks. Even with the higher quality sopranos, I'm always afraid that they'll bend in my hands when getting the neck on and off.

    Thanks Mark, guess I overlooked #2. Anyone try that on pads or chimneys ?

    Grumps, noted thanks.

    I have been the recipient of extreme nastiness from a NAPBIRT member - stuff that the organisation IMO should have kicked him out for. (A certain yellow-dyed, high profile person has more than hair in common. ) My respect for NAPBIRT took a huge dive.

    Blowhard fraudsters abound. That's why I keep qualifying my statement in terms of finding a reputable tech.

    Someone like Gordon, for example...

I've tried putting a leak light in it and examining it in a dark room, but all the pads appear to seal correctly, and I couldn't find a leak at all. Any tips?
    I just had my G1 stop playing right at the end of a gig. I later put it on a leak light and found nothing. It turned out that the G#1 wasn't closing completely when I played the G1. The cork had fallen off the G#1 lever. Of course the G#1 closed completely when I played the lower notes and the higher notes don't depend on the G#1 closing. The problem only occurred when I tried to play G1. The takeaway is to look for keys that aren't closed when they are supposed to be. You may not see a leak when everything is held down, but some key may not be closing when it should. I'm just an amateur at this stuff, but my sax is broken half the time so I'm getting some skills.

    I haven't, but I suppose one could make a solution of saddle soap and water, then brush it liberally onto the horn with the bell plugged and mouthpiece removed. Blow gently into the horn and see if bubbles appear. It would probably require an assistant to see if and where bubbles were appearing.

    There would be several issues with this. The "soapiness" might loosen corks and felts. The solution would go down tubes and wet the steel rods, causing them to rust. And soaking-wet pads form too deep of a tone hole seat (strapping down a soggy pad is a hack solution to a poorly floated pad). Too many downsides to trying the "whole horn" soap bubble test.

    I would limit it to things like the neck tenon. One of the standard self-tests is to put cork grease on the neck to see if the horn plays better. Both messy and subjective. This might be a place where a little soapy water on the neck tenon, and blowing low Bbb with the bell plugged, might quickly tell you if your neck is leaking.

    What about the cigar test? Does anyone still do that? I was going to have someone blow (pleasant smelling) vape smoke into my sax once, but I found the leaks.

    Mark, personally I didn’t find applying soap solution all over a saxophone very appealing. I see more drawbacks than benefits. However I was curious if anybody had attempted this. Execution of soapy solution on the neck was perfect for the task.

    Lutemann, A pleasant smelling a cigar?What about that smoke or fog solution used on stage? Anyone have a go of that? Somehow having a sax reek of cigars or Vape is not appealing. No matter what flavor of Tutti Frutti.

    If you suspect your neck tenon is leaking, just take it to your tech and have him test it with the Neck Leak Isolator. If a leak is found you can have it fixed right there. Or you may want to invest in your own. You can charge your sax player friends $10 each time they want to use it and you can recoup the cost in no time.
