The HZ-1 is a bit of an oddball in the Snark line-up, smaller than most of Snark clip-ons and with a slimmer clip. It offers very basic functionality augmented by a cute but awkwardly-implemented Hertz tuning feature.
The familiar blue Snark SN-1 has been around since at least 2010. It’s got a sharp, colorful LCD display, but we’re wary of frequent reports of quality and durability issues.
Snark’s lone pedal is a basic tuner with an unusual art-deco vibe, but Snark’s failure to disclose detection accuracy and detection range specs leave us tuned out.
Snark released the blue SN-1X in 2016 as an update to the SN-1, claiming a faster processing chip and high-definition screen — although we prefer the display on the SN-1.
Released in 2016, the black SN-5X offers very basic features (it cannot be calibrated and offers no transposition options, no metronome and no built-in mic) and is intended for use with bass and guitar.
The red ST-2 is Snark’s “Super Tight®” 2016 update to the all-instrument SN-2, promising a “faster chip” and “more accuracy” than previous versions. Its precision is difficult to quantify, however, since Snark does not publish accuracy specs.
The black ST-8 Super Tight is another in Snark’s mystifying line-up of clip-on tuners. Its specs are similar to the red ST-2, but the ST-8 lacks that model’s built-in mic and has a lower-resolution display.
