This more like a review than a specific recommendation. I have been using the brand new Korg AW-LT100B clip on tuner that was sent to the distributors a month ago.
Korg says it was designed specifically for bass frequencies. There is a separate guitar model.
This tuner is very light. It uses a single AAA battery unlike most tuners which use the CR2032. However the battery compartment cover is very flimsy and awkward to put back on. If any of the small slot tabs on the cover ever break or crack the tuner would be useless. The spring clip is a bit stronger than the one on the PitchCrow.
I really like the display on this tuner. It is bright and quick to react and you can chose the strobe display or the regular graduated display meter. No problem detecting the E string unlike some other clip-on tuners.There is a wide range of display adjustments which should cover any kind of headstock mounting locations. More details below the photo:
I compared the accuracy of this new Korg with the bass settings on Snark, Fender, Uber and three or four other types I have lying around. I really did not notice any difference, despite the Korg's specially designed circuit just for bass frequencies. Maybe the strobe setting is a better indicator.
The biggest problem I have found with it however, is the on/off switch. Korg uses a triangular shaped shuttle switch on the left side of the tuner display. There is also one on the right side of the display to calibrate the tuner up and down from 440hz. But to turn these shuttle switches on and off you have to use a twisting motion up and down rather than press an on/off button. Unfortunately, because the tuner is so light, the twisting motion with one hand can easily move the tuner or pull it off the headstock. In order to not move the tuner from where it is mounted, I had to use two hands. Not very practical.
Other than that, I love the display. But I eventually went back to another of my tuners (AT100 from 440 Technologies) for my P Bass. I use the Snark SuperTight on my upright. Both have regular on/off buttons.The low-priced Fender is also very good on both basses.
The new Korg is competitively priced with many other tuners in the $18.00-20.00 range. If you are OK with the shuttle switch system I am sure you will like the new Korg AW-LT100B bass tuner.
