Frequently Asked Questions

All harmonicas aren't shaped the same...We would love if the TurboLid fit all harmonicas, but unfortunately some need adjustments, or won't fit. That's why we are working to increase the list to include all of your favorites, and making modifications where we can.
Hohner Crossover The harmonica is too small. Shims are needed on both the width and the length of the harmonica. We offer a modified version called the TurboCrossover
Hohner Marine Band The harmonica body is not wide enough. A shim is needed to keep the harmonica from slipping out of place.  We offer a modified version called the TurboMB
Suzuki Manji The comb is too wide. The width of the harmonica needs to be filed down in order to fit. We offer a modified version called the TurboManji
Suzuki ProMaster The comb is too wide. The width is just 1mm too wide. The width would need to be filed down in order to fit.
Suzuki Olive The harmonica body is too large.
Seydel Blues Session Steel The harmonica body is too large.


Not exactly....as you can imagine, we've had many requests for a Lee Oskar TurboLid. We would definitely consider making one if not for the tremendous cost of tooling. So, we've worked backwards and in a more economic fashion.  Dr. Antaki has created a tooling process to trim/grind down LO plates to fit within a comb, so as to fit within the existing TurboLid.  The result is the TurboLX.


There are two styles, an old and a new. The TurboLid will fit the old style, but not the new, which is based on the Hohner MS system. You can check yourself by measuring the dimensions of the comb. If it is about 100 mm wide then it will fit. If 104 mm wide, then it will be too big (by 4 mm, surprisingly enough).


Most harmonica players are taught to hold the harmonica (primarily) in the left hand, while some hold it in their right hand and use the left for vibratos, wah-wahs, etc. The Turbolid was designed for players who hold the harp in their left hands. The larger end is intended to go at the bass end. This provides additional resonance to the bass notes and clearance to the 1-reed, thereby reducing buzzing. But the Turbolid can be attached to the harp either way. We have a few satisfied customers who use it "backwards."

About PowerBender Tunings

Invented by famous harmonica player Brendan Power, PowerBender Tuning builds on the best parts of the traditional Richter Tuning while altering the scale to make the real juicy and important notes much easier to obtain throughout the whole three octave range.


  • Same familiar breathing pattern in the upper-middle registers
  • All draw notes bend everywhere, holes 1-10
  • On the un-valved version you can overblow every hole 1-10, for full chromatic playing
  • Overdraws and blow bends are no longer possible or needed on a PowerBender - they are replaced with simple draw bends
  • On the half-valved version, a mix of normal draw bends and valved blow bends gives full chromatic-ism
  • Top octave easy to play (intuitive) as many familiar phrasings can be adopted from the bottom octaves
  • Easy to play in the common positions: 1st, 2nd, 3rd, 4th, 5th, 6th, 11th, and 12th

How to Operate

It's super easy - just press the button!
You can press the button before blowing to play a fixed pitch or while you're blowing to produce a bend.


  • Press the button repeatedly while blowing to produce a tremolo effect. It sounds like a Hammond organ
  • Play a chord, then bend all the notes at once for a slow-motion effect
  • Try bending any of the lower notes in the usual fashion, then depress the slide: notice how they go even lower!
  • You can also press first, bend later.

How it Works

The TurboSlide represents a new generation of harmonica, somewhat adopting the characteristics of both the diatonic and chromatic harp. By sliding our patented magnet toward/away from the reed, the pitch can be adjusted manually.
The current version of the TurboSlide is equipped with 10 magnets attached to a common carriage - one magnet for each blow reed (we're currently working on a model with draw reeds included in the system as well).
Putting it all together, the current version of the TurboSlide provides the "missing" flatted semitones on the blow notes and greater control over the blow bends of the top register.

TurboAx/S20 User Guide
Frequently Asked Questions

The TurboLiner, an integral part of the TurboAX/S20, is a precision etched stainless-steel plate that is bonded to the face of each reedplate of the harmonica. It is not available separately. Based on the figure on our website, the TurboLiner is easily mistaken for a gasket. But if you look again, you will realize that only one of the two TurboLiner's is located between the reed plate and comb.


Usually we will lower the gap on the reeds relevant to the notes affected. We will also apply "TurboTape" to some of the reeds to increase their stability lest they squeak, squawk, or squeal.


The setup primarily involves two things; one is the addition of TurboTape, which is generally a good thing, and has no known side effects (like make regular bends or regular notes harder or any other such thing). Second is setting gaps, which will involve the usual tradeoff between ease of overdraw/blow and risk of "choking" when attacking a note quickly. If you're learning overblows, part of the finesse is learning how to manipulate your mouth (tongue) muscles to achieve the note you are seeking. By closing the gap of the reed, the overblows become more achievable for a range (albeit small) of embouchures. But, if you attack a note with a constricted embouchure (with tongue forward), you might unexpectedly get an overblow note, whereas you might have previously gotten a straight blow note.... or nothing at all.
In either case, it's a good idea to learn to adjust your reed gaps to your taste. And the TurboLid makes it really simple to get to the reeds to make the adjustment.


The limited key availability is due to the reed dimensions. TurboHarp requires a special stainless steel plate to be attached to both reedplates. Since the Hohner reedplates come in two sizes, having shorter reeds for keys D and above, we cannot fit our existing plate to their plate. If demand were great enough, we would consider tooling up for the higher keys.

That's easy.... Shop the TurboAX/S20

How it Works

The secret of the TuneMaster is… magnetism! It is actually based on the same patented magnetic technology as our TurboSlide harp but with two main differences.
In both harps, each of the reeds has one small magnet hovering above it, by about 1-1.5 mm. The resulting magnetic attraction does two things: it pulls on the reed, and “softens” its stiffness. The softening effect is due to the “negative stiffness” of the magnet that, combined with the positive, elastic stiffness of the reed has the same effect as the traditional tuning practice sanding or scraping the root of the reed. (Negative? Stiffness? Yes, think about this: when you pull on a spring, it wants to pull back. When you pull a magnet off your refrigerator, it doesn’t pull back… but lets go.)
The “pulling” effect is the other consequence of the magnet. But this is more of a negative side effect, because it alters the resting gap or offset. On the top side of the harmonica, the magnetic attraction pulls the blow reeds shut; and on the bottom side, it pulls the draw reeds open. Just a little bit. Yet enough to sometimes prevent the blow reeds from sounding (causing them to “choke”); and sometimes causes the draw reeds to feel leaky. Therefore I find it necessary to, sometimes, adjust the resting gap, ever so slightly by poking (the blow reeds) or prying (the draw reed) … gently.
The other “secret” of the TuneMaster, by the way, are the Stainless Steel reeds of the harp. That is why it is based on the Seydel Session Steel.
By the way. Because the TuneMaster is so new, we really don’t appreciate all it can do, and all you can do with it. So we really appreciate your feedback and creative suggestions. Feel free to play around with the tuning… its virtually impossible to cause damage; and even if you do, we will fix it for you.

Frequently Asked Questions

Yes! And as a matter of fact this was the main reason that it took so long to develop The TuneMaster… figuring out the puzzle of inserting the bottom magnets inside the harmonica cover plates.


No. Unlike the TurboSlide, which has magnets on a rack that slides left and right, these magnets are in a fixed position laterally.


Possibly. It has been on our to-do list for years. (As has been The TuneMaster.) If the harmonica gods are willing… we will get to it eventually.


Yes. See below...


You might do this for two reasons. Lets break it down. If you wish to remove the magnets because you don’t like having them, and want to return the harmonica to its original state, then one of two things will happen. Either (a) the entire harp will increase in pitch by a semitone (e.g. from Bb to B); or (b) the entire harp will increase in pitch by 50 cents. In case (a) you can simply play the harp as-is, albeit in a different key. In case (b) you need to unfortunately retune each of the reeds the old fashioned way, by either raising or lowering the pitch (filing the tip or the root). I would advise raising the pitch (filing the tip.)


Yes, totally. This is a perfect job for The TurboSlide.


Yes, in most cases, you can lower the pitch a semitone to flatten the 3rd, 5th, 7th, etc… unless the reeds start buzzing.


To be honest… possibly. This is one of the reasons that we offer a 60 Day Satisfaction Guarantee. There are two reasons. One reason is that the springy-ness of the magnets is non-linear. Meaning that it depends on the magnitude of the excursion of the reeds. Hence the pitch might be affected by how hard you play. The second reason is because the magnets might open or close the resting gaps of the reeds, which might cause them to seem leaky, or to choke. This is usually easily correctible with a little re-gapping.


Not right now. We like to use Seydel's Session Steel because we rely on the stainless steel reeds, which are slightly magnetic, unlike every other harp which uses brass, phosphor bronze, or other alloys. But maybe in the future.


It's because each harp is assembled by hand, to order. Normally, I try to turn around orders within a week but rarely more than three weeks. Thanks in advance for your patience.


Good question. It's because The TuneMaster uses twice the number of magnets, which are surprisingly expensive, and also requires twice the amount of work to assemble and set up.


You are welcome to return it within 60 days for a full refund. This is twice as long as our usual 30 Day Satisfaction Guarantee.

Bahnson Overblow II - The TurboHarp Version

Bahnson
Overblow II

The TurboHarp Version

The "Overblow Harp" was designed by cardiac surgeon, Dr. Henry Bahnson in 1990. The aim was to make the "missing notes" available for the average player on the diatonic harmonica-- that Howard Levy was hitting with great facility. He knew other notes were available on the ten-holer but the same tones were available by normal playing.
The first overblow harmonica was hand-filed and the first batch of one hundred cost over $120 each to make. They have all been either sold or given away, and are currently very rare to find in circulation.
We have developed a more economical version with the same functionality as the original. This harp is based on a Hohner Special 20 and features a slide valve mechanism that, like training wheels on a kid’s bike, can make overblowing so much easier (10 times, Yerxa once said).
Project Status: Commercial prototype completed. Currently seeking investors or industrial partners. Email Us info@turboharp.com if interested.
