    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
