Qwik Tune Chromatic Guitar Tuner

There's an Automatic Guitar tuner version of this (which is silver-coloured, not gold), but should you need a dBGDGD, drop-D or need to come down a semitone down from standard - something other than eBGDAE, then give this a look. As well as the display there are LED's to show whether you are flat/sharp (within 50 cents). Electric instruments can be plugged in directly at the top (thus you can tune quietly) whilst there is a built-in mic to pick up on the acoustics. Via the latter the device does struggle to pick up on the lower pitches, and when tuning, the note can often alternate between right and wrong - the wrong tends to be fifths for reasons which might trouble those new to playing an instrument. The on/off button is not that responsive, and sometimes the symbol indicating low on battery power shows when there is still some usage left from the 2 AAA batteries it requires. The pitch pipe (ascending in semitones from middle C) can help those adjusting to tuning by ear and is handy for having around, so as to make sure things are pitch-perfect!
