Handles the low strings well
I play both cello and basses and this the best clip-on tuner I’ve found, and at a great price. Many tuners claim to do basses but struggle with the E string. This one responds very well. No frills - none needed.

Perfect on Electric Bass
OK - this was dead cheap - a tenner or so. I've been getting really frustrated with by guitar clip-on tuner, as it never recognised the low E from my any of my basses, and even the A stings on one of the basses was a challenge. So - even though this is supposed to be for cello/double-bass (clipped to the bridge on those instruments) it works EXCEPTIONALLY well, clipped to the headstock of my electric bass. Best tuner I everbought!

Nice tuner
Works well & tunes my cello with no problems. Have other D’Addario items & found them to be good quality & last for many years

Highly recommended
This has changed my life for the better, had been using a tuning fork, and/or tuning app, but this clips straight on the bridge, and my cello sounds superb now. Absolutely fabulous.

Accurate enough, and better for it
I already have the D’addario pedal tuner, which is highly accurate - but even with a bass the signal flickers between micro- frequency differences for ages before it settles. This clip-on tuner doesn’t - it gives a far more stable reading. So it probably isn’t as accurate in an infinitesimal way, but in terms of knowing your strings are correctly tuned it is simply more effective and practical.

Won’t turn on
6 months old and now won’t work. Tried new batteries and nothing helps.

Excellent and very accurate
It works exceptionally well. Easy, just clip on. And compared to a stobe tuner, it was spot on accuracy. Really can't be beat for the price
