S.o.s. Guitar Tuner

The revolutionary Planet Waves S.O.S. Guitar Tuner pulses two out-of-phase LED light beams directly onto the vibrating string. When the string is out of tune the two lights will visually dance on the string being tuned. As you approach in-tune status the movement slows down and eventually stops when you are perfectly in tune. This revolutionary visual tuning system enables precision tuning in silent or noisy environments with the need for audible sound or sensing of any kind. Features: Ergonomic pick-sized design Light Based Tuning Precisely tune in dark or noisy environments
Customer Review: You get what you pay for
S.o.s. Guitar Tuner It certainly is cheap but as a tuner it has some pretty severe limitations. If one or more of the stings on your guitar are in tune, or very close to it, then this gadget can be useful, but there are situations where it's basically completely useless. If a string is way out of tune and there's enough noise around you that you can't hear the string and compare it to others you could spend an hour trying to find the right pitch and never find it, or you could just keep twisting the tuner until the string snaps. Even under optimal conditions, it's much harder and time-consuming to use than most tuners. I can tune much faster and just about as accurately using a pitch pipe. This tuner does have an advantage over many otherwise superior tuners in that you can use it in low light situations, but that hardly excuses its shortcomings. I suggest you spend a little more and get something that works faster and better. For example, the Intellitouch PT1 and PT2 tuners are way better than this thing. I haven't tried the Intelli IMT500 Backlit Clip Style Tuner, but it looks like it matches up well against the Intellitouch models and comes at a more affordable price.
Customer Review: Good for a cheap strobe
This thing works great for a cheap strobe tuner. It works approximately like any other strobe tuner, and takes some getting used to; but I really like it. The needle in my chromatic tuner (a needle drawn on an LCD) wobbles a lot and when it's "close" the display stays stable; with this I can fine-tune a bit. I really find this thing useful with relative tuning; once I get the low E string in tune, I can use the strobe to check the A string and also visually and audibly compare it to low E at fret 5. I can use it on its own or use a chromatic tuner like the Korg GA-40 to give me a second type of visual reference. If you need to do non-standard tuning, you'll have to use the strobe against a fretted string; for Drop D tuning, for example, you'll need to fret the low E at 2 and use E6 for comparison. If you want to tune up, i.e. have low E play an F, you'll have to fret it up to D5 (fret 4 in this case). Make sure your intonation's proper if you do this.

Information About The Theremin

If you want to start learning how to play the Theremin, you must be ready to dedicate time to master the tricky hand and finger manipulations. Of course, it's fun to discover all the sounds the Theremin is capable of making! You can use your skills with the Theremin in any walk of music - from recording to live orchestras there is an overwhelming need for gifted Theremin players!

The modern Theremin is set up as such: There are two antennas, the right and left. The right antenna, which is vertical and looks like a rod, converts the players right hand into varying pitches. The left antenna, which is horizontal and hoop-like, lets the players left hand control the volume. For left handed people, the Theremin is reversed.

Theremins are still popular instruments today, for their potential is seemingly endless. Theremins can create great special effects, but they can also be used to perform avant-garde and progressive music.

Visually speaking, the Theremin is fun because the sound is produced from moving hands in "thin air". The Theremin is never touched. Imagine playing air guitar - wouldn't it be awesome if real guitar sounds occurred while air-guitaring? The Theremin actually DOES create sound when playing in air, and its sci-fi, futuristic appearance only adds to the appeal.

The Theremin is actually a complicated instrument to play. Like all musical instruments, dedication, practice, and commitment are required ingredients to play a Theremin successfully. While there aren't as many Theremin instructors as say, flute instructors, there is still a decent amount of teachers that can give you professional guidance.

Theremins are amazing instruments that are very underappreciated. Developed in the early 20th century, Leon Theremin (a Russian who moved to America) discovered that by arranging antennas in a certain way, and by capitalizing on radio frequency via RF machines, sound can be controlled.

Theremins can hardly be discussed without mentioning Clara Rockmore, the legendary Theremist who created many of the techniques to create constant, clear, and varied Theremin sounds. Many of the best Theremin music books were created by her, and they are still available today.
