Place directly on any 12" record and accurately adjust speed with the exposed record being played in order to account for stylus drag!
The KAB SpeedStrobe was designed to replace and improve upon older strobe designs that relied on power line frequency. KAB also wanted something that was easier to use and included the ability to actually measure small amounts of error. Not just a go-no-go test.
The KAB SpeedStrobe features a quartz locked illuminator with 99.99% accuracy. And since it is battery operated, it works everywhere. No need for 50 or 60 Hz versions. The disc is silk screen printed on durable 20 mil PVC. Instead of hypnotic bars, the KAB SpeedStrobe features the actual speed numbers. In use, the desired speed is read directly from the disc; no searching for the right band.

So simple, even a lawyer or an audio reviewer can't manage to screw it up!
All you have to do is place the disc on your turntable platter, start it up, point the strobe light at the disc and see the speed of your turntable appear magically as it slowly drifts to the left (too fast), the right (too slow), or remains stationary (just right, says baby bear). If your turntable's speed is adjustable, change the speed so the drift in either direction stops. I used it to set the speed on my VPI Super Scoutmaster for both 33.3 and 45 rpm and now it's 99.99% accurate. What does that translate into musically? Drums sound accurate, guitars sound right and the vocal pitch of the singers are dead on.
For the price, this thing is a no-brainer; it works with no muss, no fuss, and takes only a few minutes to get your speed calibrated properly. Trust me, this is one accessory that is both indispensable and works like a charm.

I am always very leery of audio reviewers - too many of them have never met a product they don't like...
The trouble with most speed test devices is that the strobe runs on house current - the same current your TT runs on. If the house current is above or below 60 Hz, your TT speed may be off, and so will your tester, so you won't be able to detect the error.
The strobe in this unit is driven by a battery-powered crystal-controlled oscillator, so it is independent of household electricity.
I have a superb TT - a VPI HRX with a stable AC controller. When I set my stable TT power supply to 60 Hz, you would think the TT would run right on speed, right? WRONG! I was running 3% slow! You see, it isn't just the power line frequency that determines speed - it is also everything else in the mechanical chain - pulleys, belt size, friction, etc. This device allowed me to set my speed precisely and easily - what a great tool! BUY ONE NOW!!!
