BACKGROUND
Since the very origins of the harmonica, dating back to the early Chinese Sheng 3000 years
ago, its physical principles of operation have remained basically unchanged. The sound
generator, the free reed, produces a note by periodically interrupting the flow of air through the
instrument. The pitch of the note produced by reed is determined by three factors: its mass, its
stiffness, and the resonance of the air path (which includes the player’s oral cavity.)

As you are probably aware, the player may alter the mass and stiffness the reeds by sanding,
scraping or filing material from either the tip or the root, respectively. He/she may also modulate
the resonance of the air path through bending or overbending.

By appropriately altering his/her embouchure, a player can achieve several of the “missing”
notes not normally provided by the diatonic scale. Some notes may be “bent” lower, others
“overblown” or “overblown” higher. These are summarized in the diagram below:
The lower “bendable” notes typically provide a smooth transition between the natural pitch of
the draw reed and approximately a semitone below the pitch of the blow reed. The bends on
the upper register, as well as the overblows and overdraws involve more sudden transition of
pitch.

The Chromatic harmonica offers additional possibilities by providing additional reeds in each of
the sound holes. A valved plate is typically needed to toggle between the natural note and a
sharped note. Again, this provides a sudden transition of pitch, precluding a gradual transition
and hence limiting the expression of the player.
HOW IT WORKS
The TurboSlide represents a NEW generation of harmonica, somewhat adopting the
characteristics of both the Diatonic and Chromatic harp. The physical principle of its operation
is shown schematically below:

The TurboSlide employs a permanent magnet adjacent to the reed to alter its stiffness. From
the diagram you can see that the relationship of force to displacement which is normally a
straight line becomes more shallow when the magnetic force is added to it. Lower stiffness
means lower pitch.

Then by sliding the magnet towards/away from the reed, the pitch can be adjusted
manually. The current version TurboSlide is equipped with ten* magnets attached to
a common carriage. One magnet for each blow reed. (For reasons explained later,
this model does not include magnets on the draw reeds.)

OK, you might be wondering why there are no magnets on the draw reeds. There
are two reasons. One is that the draw reeds, at least on the lower register, are
already easy to bend. Therefore there is not as big an advantage of a slide. On the
other hand you might ask, “why not use the magnet in the opposite direction, to
make the note sharper?” This is indeed technically possible, but more difficult. We
therefore plan to add this feature in a later version of the TurboSlide harp.
Putting it all together, the current version of the TurboSlide provides the “missing”
flatted semitones on the blow notes (red box below) and greater control over the
bent notes of the top register (dotted box below.)

Slowly for soulful expression... or rapidly, to introduce tremolo.... One at a
time; or all at once... By a half-step, or even whole step!
Better yet, because the TurboSlide allows the altered notes to be phased
in/out at will, the player is offered the ability to bend any of these notes
smoothly.

Two models of TurboSlide
Model: TH-09
The original TurboSlide, introduced in
November 2010 based on the Seydel Silver+.
It was chosen due to its stainless steel reeds
which are intrinsically paramagnetic. It is also
very high quality instrument, but comes at a
premium price. However it provides bending of
all 10-blow notes, and on certain models
allows the player to adjust tuning of individual
reeds through the use of a screw adjustment.
Model: TH-09a
Introduced in October 2011, this version is
based on the Hohner Special-20 harmonica. It
was motivated to reduce the cost of the
flagship TurboSlide, and also to provide our
customers with the TurboLid enclosure which
they have grown to love. Because the reeds
are not magnetic, a small drop of magnetic
coating is applied near their tips. This model
only provides magnets on the first 6 blow
notes (holes 1 through 6), and does not allow
tuning adjustment. (We figure that since holes
7-10 are already bend-able in the conventional
manner, it cost/benefit of adding magnets to
these reeds would be too great.)

TurboSlide of the Future
Here are some additional features from our development bench that we plan to add to future versions of the
TurboSlide:
1. Ability to bend (flatten) the draw notes. Although these notes are already bendable in the conventional
fashion; there is an advantage to the TurboSlide feature, namely: the ability to bend them all at once,
introduce tremolo, and special tunings.
2. Ability to sharpen (bend up) the blow reeds. This is technically more difficult, and has not yet been
perfected. If successful, it would provide a true “whammy bar” effect.
3. Static version: concealed magnets without slide, to allow easy tuning of reeds without filing.
4. You tell us! What features would you like to see? We’re always listening.

OPERATING INSTRUCTIONS
Its really very simple... and almost self explanatory. Just press the button, in the direction shown. You may
press the button before blowing to play a fixed pitch, or while you’re blowing to produce a bend. Think of it
as a whammy bar for the harmonica.
Here are a few additional fun things to try:
1. Press the button repeatedly while blowing to produce a tremolo effect. It almost sounds like a Hammond
organ.
2. Play a chord, then bend all the notes at once... a “slow motion” effect.
3. Try bending any of the lower notes on the harp in the usual fashion, then depress the slide: notice how
they go even lower! (You can also press first, bend later.)
4. If you’re in to overblowing, try pressing the slide just before attempting to overblow. Notice how much
easier they are to hit perfectly.
The possibilities have yet to be explored. Let us know what you discover!
MAINTENANCE
The TurboSlideTM should be treated with care... like any other harp. The exterior can be cleaned with a soft
cloth. The interior may be rinsed with water, the internal parts are corrosion resistant. If you wish to
remove the cover plates, help yourself – but please pay close attention to how everything fits together. It
takes a bit of finesse to get the slide to operate smoothly without sticking.
PRECAUTIONS
• Because the The TurboSlideTM employs high-strength permanent magnets, although small, it is advisable not to place your
credit card or ATM card in near proximity: like next to your wallet. There have yet been any reports of this happening, but
better safe than sorry.
• If adjusting the setscrews, do not overtighten so as to permit the magnet to poke out the bottom of the rack. This will distort
the rack, and probably get caught when you press the slide.

TUNING & TWEAKS – TH09 (Seydel Version)
Tuning: 0n some models of the TH-091, the degree of bending (bend depth) of the TurboSlide can be altered somewhat by
adjusting the tuning magnets. To do this, you must first remove the cover plates. A small Phillips screwdriver has been
supplied for this purpose. Once removed, the magnet rack is exposed in which there are ten small screws containing the
magnets. Loosening the screws will diminish the flattening effect; while tightening will accentuate the effect. But be advised
that the screws do not have a lower “stop.” Therefore you should be careful not to over tighten. If you see the rack
bending as you tighten, or see the magnet protruding out the bottom, you’ve gone too far. This will not damage
the harp, but will throw off the tuning of all the other reeds.
Replacing Magnets: Your harp should have come with at least one “spare” magnet.* In the event that something happens to
one of the magnets, for example if the threads or screw slot becomes stripped. Replacing the magnet should normally be a
simple matter of unscrewing the old one out, and the other back in its place. The TurboSlide is usually shipped with high-
power magnets. Although they can be adjusted,* you might find they are just a little bit “too” strong. We also supply optional
“medium” and “low” power magnets which can be easily swapped in. You can purchase replacement magnets on our
website, or by contacting us directly.
Stiffness. The slide lever is intentionally designed to be stiff, so as to provide force-feedback the player. But you might prefer a
softer response. There are two ways to do this. One is to remove the screw marked “A” on the diagram below. This will
eliminate the right most leaf spring from the mechanism. The screw can be left out without affecting the function of the
harp. If you wish to make this permanent, you can simply “prune” the leaf spring with wire cutters, a sharp razor blade, or
nail clippers.
Stiction. If you find that the slide mechanism become “sticky,” it might be caused by over tightened retaining screws. Try
loosening screws D, B, and Aone a time to see if this solves the problem. Only a tiny twist will have a big effect. (Note,
screw Cis not currently used.) Another possibility is that the cover plates have become a little crushed (like when you sit on
it. Try sliding a piece of paper between the plastic magnet rack and cover plate. If it does not fit easily, then gently pry open
the cover plate just a tiny bit and try again. A

Reed Gapping. Due to the attractive force of the TurboSlide
magnets, they tend to reduce the gap of the reed when the
slide is depressed. Sometimes this can cause the reed to
“choke.” If you find this to be the case, you might try enlarging
the gap slightly. Instructions how to do this are available on
several websites, including ours.
If you run into any kind of trouble, don't hesitate to contact us. We are committed to
making your TurboSlide experience a satisfying one. If we cannot solve your problem
remotely, we are pleased to service your harp in our shop.

TUNING & TWEAKS – TH09a (Special-20 Version)
Tuning: You will notice that the blow reeds of the TurboSlide have a black spot on them, near the tip. This is
a paramagnetic coating that was applied to give the magnets something to “pull” on. If you ever need to
retune a reed using the typical technique of filing the tip or root, be careful not to chip or scratch this black
spot.
