Here's a video on how a strobe tuner works:īasically, what it's doing is creating a real-time visual representation of beat frequencies between a played note and a reference frequency (implemented as a spinning disk RPM). The unit can be calibrated by using an internal calibration circuit that sets the strobe flashing at a fixed value (probably 440Hz) and then a calibration knob can be used to fine tune a correction to the RPM, but ever since I sent this thing in for a factory refurbish, there has been zero need to adjust it. If it's off just a tiny bit because the note is sharp or flat, then it looks like the disk is slowly turning to the right or left, depending. If the flashing is happening at the speed of the rotating disk (or twice that rate or 4 times, etc.) then it looks like the disk is standing still. Behind the disk, a series of small neon bulbs are activated to flash based on the waves of electric current that are the sound signal coming from the microphone. There is a specialized drive motor and associated control circuitry to hit a very precise RPM. The "reference" in the strobe tuner is a the RPMs of a spinning disk. I apologize if you already understood this. they're very different than digital tuners in mechanism. Make sure to choose the carrot color theme for best contrast. It has a needle scale with cents markers and also a digital frequency readout. I can have the TV on and the phone a few feet away from a guitar and gstrings has no trouble with the background noise. I've been using it on my 3 year old Galaxy S5 (works equally well on an even older Galaxy Note 2). If you have an Android phone, can you check the accuracy of gstrings free with your ST!!?. Hey BellyDoc, do you know what the Conn ST11 use as a reference? Does it use AC line frequency? Of course, I'll also be perfectly content with a Budweiser if craft beer isn't available, and I microwave leftover coffee from the office pot rather than make a fresh one if all I want is the one cup. 99% of the time I tune with a clip on super snark that's far less accurate and I'm happy with the result. I have an old Conn ST11 strobe tuner that's been factory repaired and runs beautifully, but it's mostly an educational aid. How much does app to app variation matter if you're solo? If the note to note frequency ratios are basically consistent then the only thing you risk is relative tuning issues with another instrument. BellyDoc wrote: ↑ Tuesday 05 September 2017, 23:10 pm
