SAVE THE HANDS!!
We've been rocking the TurboTune string winder for almost 20 years. It's been through several licensees, and was even made independently by the patent-holder for a while. Now the production and distribution has been picked up by a new, very well-known company. A longtime proponent of this great item, we were able to work a great deal to sell these in "bulk" - meaning that you're not paying an extra couple bucks for the cardboard header card (and the extra costs to ship them) - so you get the same great product, without the throwaway packaging, for less money.
Here in the shop, we often have to do quick string changes. Without this little tool, it would be a lot more of a hassle. It's wide enough to fit most upright bass tuning machine heads (though not the Sloane tuners, unfortunately) as well as most any other instrument, including guitars, electric basses, even mandolins!
I don't know about you, but all those repetitive tuner key turns wear me down. Sure, the manual crank is better than twisting with your wrists. But anyone who's ever built or repaired anything knows that the most important invention of the 20th century was the electric screwdriver. Now you can use that miracle tool to automate string changing using this handy contraption!
Or you have an excuse to go to the Home Depot/Lowes/Sears Hardware Store to buy... another one!!!! (My wife believed me when I told her I had to get me one of the cool Gyro ones in the photos. At least I think she bought it.) The Black & Decker Gyro Screwdriver totally rocks -- truly easy operation with one hand, and no buttons to fumble with. You just firmly grip it, and slightly turn your wrist. The screwdriver automatically senses your movement and starts turning that way. SUPER cool.
The current version of the Turbo Tuner is molded in a pale white color with a slight bluish hue (I've done my best to get a good photo). Why the odd color? It GLOWS IN THE DARK!
As for operation, as you can see, the crank separates from the business end of the unit so you can exercise your electric screwdriver instead of your hands. It has the added advantage of enabling one-hand, more controlled winding, because you can use your other hand to better guide the string onto the roller.
It can, of course, also be used with the included hand crank. See photo to see how the two halves just pull apart, and you insert the tuning chock into a electric screwdriver (the chock has a standard hex end) as well as what the unit looks like fully assembled with the crank, above and to the left.
The head is approx. 7/8 inch across.
I guess you can tell I like the TurboTune. You will, too.
Note that the Turbo Tuner's multi-faceted chock fits almost all tuners, from tiny mandolin pegs all the way up to upright bass. However, we have confirmed that Sloane double bass tuners are just a bit too thick and the Turbo Tune won't fit those without modification (folks have used a thin file to slightly widen the opening and had success, but you perform this modification at your own risk).
This is the best string winder on the market. It's indispensible for upright bass string changes -- the drill adapter makes it a snap to neatly wind the new strings onto your tuning pegs without triggering carpal tunnel syndrome. What I didn't expect was how useful it would be for changing strings on my electric basses and guitars. The part that engages with the tuning pegs has several different slots that snugly hold everything from vintage Fender style bass tuners to various 6-string guitar tuning knobs, and the plastic it's made of won't scratch the finish of your fine guitars, unlike cheaper tuners. A must have!
Doesn't work well for fatter tuners like those found on my Kolstein Fendt. The winder's plastic has enough flexibility to fit the pegs, but it's constantly pushing them out; probably not great for the lifespan of the winder. Works great on Fender style tuners and Gotoh tuners.
This is a very handy tool and will save your wrists during string changes. I've used it both with the included hand lever, and as well with an electric drill. With a drill (at the slowest speed!), the string change was a breeze and quick. With the hand lever, string changes were still comfortable. Without this... ouch, my wrists! A must have.
I don't know why it took me so long to order one of these. It saves so much time and effort, especially with the power driver adapter that is built-in. Trust your instincts, it's worth it!
I bought this to save time and effort when changing strings on the URB, and when attached to a power drill is most certainly does that. Also works rather well with electric bass.
