Really nice tuner. I did not trust it at the beginning and bought it to use on Ukulele but then I tried it also on my bass and it works :-) It's small so it'll fit in any pocket of gigbag. Very readable screen, have 2 settings for Ukulele but in chromatic mode can be definitely used for bass, though I'm not sure if it'll handle low B as I do not own 5-string low B bass. On 4 string bass and high C works great. Compared it with my Zoom B3 tuner and was amazed how well it tracks, as I thought clip tuners can't work better or on par with pedal tuners... Well I was wrong, that's really great product for great price. Manufacturing quality is good, it includes battery already, so it's ready to work after you open package.
