GO FOR THE GOLD & IMPROVE YOUR TONE

The thin film that covers the pads affects the tone of your flute and the tonal qualities of Gold are well known to be beneficial. Now you can enhance the tone of your flute by replacing tone deadening animal skin with Gold which is more acoustically reflective and resonant. Bladderskin hurts your tone and absorbs some of your precious sound and energy. Gold reflects all of that beautiful sound to the listening audience. What you get is a focused, well-centered tone that is rich, resonant and warm. Recover your lost tone by installing reliable JS Gold pads - it's the best thing you can do for your flute.

Gold is also beautiful and does not tarnish. Now you can have the tone and beauty of gold and increase the value of your flute as well. JS pads have Gold on the surface. Metal particles are also embedded directly into the film - this high tech achievement gives you an extremely durable pad. JS pads do not tear or cut through like bladderskin does (there have been no reported skin failures so far). The flat soft surface makes a perfect and quiet seal when closed on the tone hole. Their reliability and stability gives you peace of mind because they offer a superior and dependable seal without absorbing moisture and warping like conventional pads do.

THE PAD TONE TESTER
In order to test the tone of different pads, a special instrument was created. The image at left shows a long piece of flute tubing that is full of toneholes. A special quick change pad rack was designed to fit the tube. Each cup is spring loaded and self aligning, making it possible to switch from one rack of 19 large pads to another in just a few seconds. This makes it very easy to compare the tone of various pads and pad materials. I have tested many experimental pad materials and have compared their differing tonality as well as their ability to hold air.

The ultra-thin film I use has a non-permeable, waterproof surface. It is not affected by moisture or humidity and does not swell or shrink like bladderskin pads. JS pads are very stable and do not need as much "later on" adjustment as bladderskin pads.

TONALITY
The feedback I get from professional musicians is that the tone of Gold pads is more musical and beautiful than bladderskin, that it is richer, rounder and clearly focused. Bladderskin has a dry, buzzy sound. Gold adds depth and color to the tone. Switching to Gold pads can give you as much tone improvement as you would get from switching to a higher quality headjoint.

PLAYERS
Alexa Still and Robert Dick are top players who have switched to Gold pads. Hundreds of other players are also enjoying the benefits of Gold pads. The response has been overwhelmingly positive.

TESTIMONIALS
"I've had the flute back from Brannen for a week. They did a great job with the installation. The pads are fantastic. What more can I say? The flute is more colorful and even, the pads feel great, and when I wish to play with no mechanism sound they really silent and when I wish to do key percussion, they made a very classy, loud and clear sound." Robert Dick.

"It is my pleasure to tell you that your Gold pad is like a dream. One word comes to mind when I try to describe what they sound like in my Tom Green flute, and that word is - burnished. The tone is resonant and rich and has a finer finish to the sound than I've noticed with any other pad." Dave Johnston (orchestral player in Manila).

"I got my flute back last week, now sporting JS gold pads… The response in the instrument feels somehow more instant and positive. Transitions over larger intervals are extremely smooth, almost effortless. Usually I can feel the instrument vibrating through my right thumb but now it seems to be resonating more. I can feel vibrations through all points of contact including the keys. Even the G# key! … the response is so instantaneous I find that my finger technique is more delicate and light." Dean Stallard (Pro flutist & teacher in Olso Norway).

"I am so amazed at the difference in my tone, and how easy it is to pop out those low register notes. I have received wonderful compliments on my tone by my colleagues since I've had the gold pads installed. Thank you for your great invention!" Zoe Shepherd

"I love your new pad. They don't wrinkle. They do seal, "no doubt about it"! and somehow, they sound even better. Congrats!" John Lagerquist

"The results far exceeded my expectations (which were irrationally high to begin with). The flute now actually vibrates whilst playing in the lower register! I can't say enough about the pads. Many, many thanks!" Jeff Menz

"David Williams just sent me up an 014 silver flute with your latest gold pads in it. These are really great! I immediately called Phil Unger in New York to tell him that these are a winner. He has been asking about them. In fact, I am going to have Eric at the [Williams] shop repad my gold flute with your new gold pads. Cheers," Marcus Hutchins

"I finally got a chance to install the gold pads that I ordered from you a few weeks ago. I think they are just wonderful, on all accounts. The resonance is wonderful, projection, response, the tone quality is enhanced throughout the entire range. I just finished up shimming and adjusting and I can't put my flute down because it sounds so much better. It also feels great, I feel like I don't have to force for a deep sound and I can use such a light touch because the pads cover so well and are so responsive. Wow, congratulations on this fine acheivement!!! (Plus I really love the bushings, they are so easy to use and the pads in general are so great to install because they don't wrinkle!!)" Jessica Johnson

"The fabulous Schmidt pads. I have them on two of my flutes and have been very pleased with them." Francesca Arnone

"I have just had my flute repadded with JS gold pads, and it's amazing. Hard to know whether some of this is simply having the instrument properly adjusted overall, but it seems to me that it's now playing WAY better than ever before." Jane Weber

"These pads have been stabile and sealing perfectly though an immense amount of playing, under the most extreme conditions (from central Maine in January to southern Florida to Phoenix to the West Coast) in contexts from jazz orchestra to solo recitals. Phenomenal! Thanks, and keep up the great work." Peter H Bloom

DURABILITY
There has never been a reported skin falure so far. The gold particles are embeded in the film so they will not wear away. These pads will stand the test of time and provide excellent service long after bladderskin pads have split and fallen apart.

CLEANING
The sugar in our body chemistry can build up on a pad and cause it to stick. To clean a gold pad, insert paper over the tonehole, close the cup and drag out the paper (do this when the pad is sticking). Rubbing alcohol on a cloth or alcohol swabs will also work. Gold pad film is many times more durable than bladderskin. Use magic dust to treat the pad to prevent sticking from recurring. For bladderskin or other pads that have a tendency to stick - order "JS Magic Dust" . This dry lubricant works great (it is not graphite). It is non-toxic and being a lubricant - it can only help the keywork. JS Gold pads have a small percentage of magic dust embeded into the skin along with the gold. The dry lubricant releases slowly throughout the lifetime of the pad to help prevent sticking.















Get rid of those ugly screws inside your flute bore. A small pair of powerful magnets (one attached to the retainer disc and the other to the cup) serve to hold the pad securely within the cup. The screwless metal surface of the retaining washer is more streamlined. This streamlined shape benefits the acoustical properties and projection of the flute. You wouldn't stand for deep, tone damaging scratches on the inside of your flute tube, so why should you tolerate the screw slots in your pad retainers? Another plus is that since there is no screw hole in the center, there is no possibility of leakage in this area. The magnets exert just the right amount of tension on the pad and that tension is constant. The magnetic retainer is a simple and attractive improvement over a screw and hole that can loosen, leak and fail. I welcome flute makers to contact me if they are interested in using this type of retainer. They can also be retrofitted to any brand of existing flute. Kit assemblies include magnets, magnet housings and sterling silver washers.

Here is a photo of the screw-less, quick change retainer. Note that the skin is slightly depressed evenly around the retainer with no wrinkles.




FOR YOUR BENEFIT
These great sounding, long lasting pads are here for the benefit of all who use them. It has been a long road bringing them to perfection, but it has been worth it. I am very happy to improve the world of flutists and their music in a small but important way.

JS FLUTE PAD INSTALLATION TECHNIQUE

JS pads come in 1.7mm thickness with .040" (1mm) thickness stabilizers. Delrin stabilizers ($1 each) are available in various diameters and come in .024" (.6mm), .032" (.8mm), .040" (1mm), .048" (1.2mm) and .056" (1.4mm) thicknesses. Special high strength aluminum stabilizers are also available in .020" (.5mm) or .028" (.7mm) or .040" (1.0mm) thickness at $2 each. Stabilizers must be glued into the cups so they will not move or flex. Aluminum stabilizers are stiff, flat and glue much better than Delrin.

RETAINER LEAKS
Be sure to install JS soft plastic retainer screw seals between the retaining washer and the screw head ($1 per 10 or $10 per 100 etc). These retainer seals go between the washer and the screw - not under the washer. They prevent air leaks and keep the screws from loosening. Avoid slippery teflon or paper seals.

SHIMMING
For stability, avoid more than .012" (.3mm) shim thickness). Use plastic rather than paper shims because paper can swell/shrink up to 20% with moisture/humidity changes and cause leaks. Bending/tilting the key side to side so its level the tonehole is fine but never bend it from front to back or you will distort the cup. . Pads must be shimmed within .001" (or less) of perfection. Keep partial shims to a minimum (one or two). Beware that the pad is not so tight that it must be forced into the cups or the outer ring can be damaged or dislodged. Regular pads should measure .1mm (.004”) smaller than the cups. Trill pads should measure .2mm (.008”) smaller so they can be floated in. Cups should be well centered with the toneholes or a leak will result when the tonehole is too close to a retaining washer or bushing.

OPEN HOLE CUPS
Metal bushings must be replaced with JS leakproof Delrin bushings ($1.00 each). Original Brannen or Burkart delrin bushings must also be replaced because they do not match/seal with Digital Gold pads. These bushings slide on and off smoothly and make shimming an easy job while reducing the likelihood of damaging a pad. The delrin bushings and plastic retainer screws are essential for making JS pads work because they are flexible and provide a seal against the inner collar (metal bushings will leak). Order bushings that are .1mm (.004")smaller than the outside diameter of the cup chimney. There is a hidden aluminum collar near the pad center and a special skin protector is provided with your pad order to prevent your bushing removal tool from pinching and cutting through the skin (see image).









DELRIN BUSHING KIT
Delrin bushing kits come in a 6 compartment container with 6 sizes (5 per size) from 7.6 to 8.1mm Sizes 7.5 to 8.3mm available.

Delrin bushing upgrade kits are required for Yamaha 500 series & up and for some older flutes with tapered cup chimneys (Haynes etc). Stainless steel sleeves slip over the old chimneys and provide a new straight surface for the delrin bushings.

GO TO MORE INFO ON DELRIN BUSHING UPGRADE KITS.




GASKETS
click to enlarge
Thin gaskets for bushings - to provide a tight seal for imperfect chimney/cup alignments (solves leaks in otherwise perfect pad jobs). Thin rubber gaskets are trapped between the bushing lip and the pad surface to prevent air leakage.

TRILLS
The plastic rims are very thin so take care not to overheat them or poke through them with a needle when installing. Do not use shellac for the small C# & trills because it is very brittle and can easily lose its grip on the slippery plastic. Use hot glue and check with a leak light.

NO HEAVY CLAMPING
Remember that these are not felt pads and should not be treated so. Do not use clamps on them. Do not overtighten the retaining screws or you will wrinkle/distort the pads and create leaks. If a gold pad suffers a dent or fingernail mark etc. Heat up a piece of thick flat metal in boiling water (thick so it won’t cool too fast). Then hold it against the face of the pad for a few seconds.



DIAMOND TONEHOLE FILES
Make sure that the toneholes rims are flat before installing these pads. I supply a set of excellent rotary tone hole files/pilots for this purpose. GO TO PRICES & ORDERING

JS flute tonehole files come supplied with your choice of #300, 600 or 1200 grit diamond abrasive which cuts fast and smooth. These high quality finishing discs are made of precision surface ground steel with diamonds embeded directly into the metal. These are the only files that give you a perfectly flat tonehole quickly and easily every time. Other files are a slow struggle in comparison. For a fine finish I recommend the standard 600 and then the 1200 grit finishing discs. The 300 grit discs are better for student quality flutes or general roughing in. The back side of each steel disc doubles as a surface guage to check for perfect flatness of the tonehole. Basic size pilots are supplied with the files. Inbetween size pilots in .5mm increments are also available.

DIAMOND CHAMFER TONEHOLE FILES FOR FLUTES
JS diamond chamfer files will take off the sharp corners on the inside and the outside of flute toneholes. This process is essential for creating tonehole rims that do not tear into the pad skin. There is no sandpaper to change because the diamonds are embedded directly into the metal. This means less down time and more labor savings. Be sure to place a few drops of light oil on the diamonds to help keep them from clogging. Then place the appropriate size file over the tonehole and turn. Some toneholes are out of round and it may be necessary to push towards one side so that the entire circumference of the tonehole gets de-burred (check under magnification as you go). Be careful not to take off too much metal. If the files need cleaning, use an ultrasonic cleaner (or a needle). 5 grinding surfaces are included. Each of the concave grinders has a protruding outer plastic ring which prevents accidentally scratching the flute body. JS diamond chamfer files are the perfect companions for JS diamond tonehole flatteners.

LEAK ISOLATOR FOR MAGNEHELIC
Here is the tool you need to achieve a perfect pad job. The hand held wand has two Orings that isolate each tonehole/pad one at a time as you slide it down the flute tube so you can check and compare the seal of each pad. Simply slide the wand into the flute, close the tonehole you are checking and look at the meter on the Magnehelic. Its the only tool of its kind and it is the best, fastest and easiest way to check for leaks. If you have shimmed a pad properly and a leak persists - then you may have a retainer leak (many good repairmen miss this). Adjustments can be balanced with precision. The leak isolator uses 1/2" inside diameter silicone O-rings with 3/32 wall thickness (lube with magic dust).





The Magnehelic takes out the guess work and is a huge time saver. Remember that a flute will only play as good as its worst leak allows it to play. This tool help you find that leak quickly so you can eliminate it. Now you can be certain that your customers will be satisfied.
