The TU-10 offers some nice features in this sturdy clip-on tuner, including calibration and transposition capabilities, along with Boss’ popular “Accu-Pitch” feature.
The TU-30 is Boss’ compact successor to the popular (and discontinued) TU-80, offering solid specs and numerous features including a built-in mic, metronome and beeping “Accu-Pitch” function. It lacks, however, an output jack.
D’Addario’s latest clip-on tuner is well-designed, has a nice, bright display, a solid-looking clip and can be calibrated across a 20 Hz range. But its ±3.0 cent accuracy and minimal documentation is disappointing.
D’Addario’s NS Micro is a well-designed and solidly built low-profile clip-on tuner. But poor detection accuracy and unspecified detection range leave us unimpressed.
The NS Micro Soundhole tuner is a neat idea in a nice package, but second-rate accuracy and a fragile clip design are below par for a company like D’Addario.
DeltaLab’s basic clip-on tuner offers a monochrome LCD display with a color-changing backlight. The slim clip and swivel-head make it easy to attach and adjust.
DeltaLab’s CT-30 is the color upgrade to the CT-10, offering a color LCD display, visual, tap-tempo metronome and transposition options. We also like its slimline clip and flexible swivel arm.
