T396-A Trigger Saddle Issue

Tuesday, January 21st, 2014

If you purchased  a T396-A model in the last year, we would like to let you know about a potential issue with your instrument’s trigger saddle. Our machine shop supplied us with a batch of these saddles where the back radius is too similar to the dimensions of the silver cross brace on which it sits. This prevented the flux and braze from flowing evenly under and around the brace when the horn was manufactured. This is not an issue with our most recent T396-A’s as we fixed the issue by softening the saddle’s radius, which allows the flux and braze to do their jobs.

If you purchased a T396-A between January and August 2013 — and notice a separation between the trigger saddle and the silver brace — please send us an email with pictures so that we can repair your horn before the saddle fails entirely.

This repair is necessary only if there is a separation between the saddle and the cross brace. 

We’ve posted two images below to help you determine if you need a repair. The first one shows an instrument with a noticeable gap between the cross brace and saddle. It had been repaired by an instrument tech, but I personally applied stress to the trigger to see if the repair would hold. It did not.

The second picture shows a saddle with an even application of silver braze around the joint. If your instrument looks like this, then no repair is needed.

My worst fear is hearing of a failure of one of our horns. Please check your instrument and let us know immediately if a repair is needed.

Acidity and Your Horn

In our latest video, Christan discusses ways to prevent your horn from needing costly repairs caused by high acid levels in your skin. Really. We aren’t making this up.

Please Clean Your Instrument

Wednesday, September 8th, 2010

In college, I had a friend that played a Bach 42B that smelled like death. It just about knocked me out when I got near the thing in wind ensemble rehearsals. We made fun of the guy for it, but it may not have been a laughing matter. According to a study released in Chest magazine and reported on ABC News, wind musicians, “may unknowingly inhale mold and bacteria from their instruments, which may lead to the development of hypersensitivity pneumonitis (HP).”

Doctors say that even though these results aren’t shocking, they aren’t very common. Regardless, clean your horn before it starts breeding Sea Monkeys and Chia Forests. Need more incentive? Take a look at this…

UPDATE: NPR has posted an article that provides more information on Scott Bean, the unnamed trombonist in the ABC News article.

Cool Stuff

So I’m at work with my Facebook page open in the background. I get an IM and check it out. I meet a trombone player from Chile and the next thing I get to see/hear is this:

Pretty cool. I love my job!

Risk vs. Reward: Buying a Used Edwards

Tuesday, March 24th, 2009

The recent banking woes have everyone worried about money (well, some people aren’t, but not many of them play music for a living). Many musicians that were thinking of buying an instrument have either put that thought aside or are considering buying used instead. Doing the latter will definitely save you some money, but be sure you weigh the risk vs. the reward.

We rarely have a day where we don’t hear from someone asking about a used horn they’ve just purchased. Usually, the call goes something like this:

Caller: “I’d like to ask some information about the Edwards I just purchased from Joe Schmoe.”

Christan: “Sure. Please tell me the model, serial number, bell markings, tuning slide color/shape, and slide markings.”

After receiving this information, I’ll be able to tell you quite a bit about the horn. But I probably can’t tell you how it was treated and maintained since it left our shop.

FYI, our serial numbers give you the year and month the valve section was built. For example, a bass valve section I just saw at ETW was 2904003. It was built in 1992 (I know, the year is backwards) on April 3rd.

The Edwards bass I mentioned above had very little lacquer left on it. It was clear that the horn could stand some TLC: valve work (and possible replacement), lacquer stripping, buffing, degreasing and re-lacquering. But the horn was purchased for $2500, so the buyer definitely saved some money.

If someone were to see the above horn and base their opinion of our company solely on it, they might think that Edwards quality is not what it should be. But once a horn is shipped, it is at the mercy of its owner. Many of our customers treat their horns like a member of the family, but we’ve seen more than a few coming back to us in desperate need of attention.

For the sake of argument, let’s say two T350’s were shipped the same day to “Richard” and “Linda”. Both players followed our advice and maintained their instruments properly. However, the two players couldn’t be more different…

“Richard”, a typical high school student, plays his instrument for 45-60 minutes day. We’ll round this to five hours a week. He takes summers and Christmas breaks off, so we’ll say he’s on the horn 37 weeks a year. Five hours a week for 37 weeks means “Richard” uses his horn 185 hours a year.

“Linda”, a professional trombonist, practices/performs on her instrument an average of 5 hours a day, or 30 hours a week (she gets Mondays off). Since “Linda” has to make a living on the horn, she’s off the horn far less than “Richard”, let’s say only four weeks out of the year. Thirty hours a week for 48 weeks a year means “Linda” is on the horn 1,440 hours a year.

“Richard’s” horn is the same age as “Linda’s”, but that doesn’t tell the complete story. It would take 7.8 years of the student’s practice schedule to equal one year of the professional’s. Let’s equate the student’s usage to a typical year driving a car (12,000 miles). By comparison, the professional’s car would have 93,600 miles after the first year.

Makes you wish we installed odometers!

Regardless, if you are purchasing a used Edwards that was made in 1992 — and it is now 2009 — you can be sure that there are a lot of miles on the horn. Some work may be needed to get it back to its original state. Our instruments are made to stand up to professionals, but no instrument will maintain it’s “like new” integrity with the normal usage of a pro. To current Edwards owners, you can offset the wear and tear by adhering to our maintenance schedule. Here are some highlights:

  • Have your hand slide checked and (if needed) straightened once a year. Tubes that aren’t aligned properly are the main source of premature slide wear.
  • Have your valve(s) checked every 4 to 6 years.
  • Keep all your tuning slides lubed and push them in every time you put your instrument in the case.

If you notice something not quite right with your horn, take care of the issue(s) sooner rather than later. Your instrument will work for you much longer than that of someone that neglects to maintain his/her horn. Maintaining your instrument will also maintain its resale value.

Purchasing a used instrument boils down to risk vs. reward. We want you to be happy with your Edwards whether you purchase it from us or from a third party. Just do your research and try to make the best decision. Also, keep in mind that we’re always here to help you make that decision.
