It seems that frequently, when OP's resolve their issue, there is no feedback or closure. So, FWIW, I received my Meisel 90 from Golihur's a couple of weeks ago, and it'll probably do just fine; but...
When I 1st clipped it on my bass, all strings were dead on in tune (Spriocore mittells after 2 weeks), but 1/2 step high…hmmm. Same thing when I tuned my jazz band's practice bass the next day. Except that after i re-tuned, I checked again and all strings still were 1/2 step high. What the…….????!!! So I re-tuned and checked again and tuning now read a full step low. So I tuned back up, and tuning matched the piano; so I left well enough alone, and stuck the tuner in the bag for the night.
The next day at home, I thought I should see if there was some sort of manual or something for the tuner, before complaining to the vendor. Whoever heard of having to look at a manual to use a tuner? If a manual was included with the tuner, it must have been folded very small and hidden, and I threw it away. But I soon found a PDF manual on Golihur's website (all hail!), and quickly discovered that for some strange reason it is very easy to program the tuner so that it reads either 1/2 or 1 step flat. Apparently this for people who can't play guitar and have to use capos, and are too lazy to remove the capo to tune the guitar, and are too stupid to calculate half steps in their head. Whoda thunk???? I really don't get it. It seems the capo would impede string movement, and tuning would not be accurate.
Other than that, the tuner is very precise (almost too precise). It hears the low E just fine (my original question), but sometimes gets confused on the A string and calls it E, but not so bad that I can't tell what's going on. The balance of the tuner could be better; I'm used to clipping the tuner on my music stand when not in use, but this one is a bit awkward on the music stand.
So, in general, I think I like the tuner OK, but not as much as the $12 Korg bass tuner that I lost (only hears 4 notes and hears them well), and apparently they don't make any more. I'm a bit frustrated with how it's over-engineered to do too many things that nobody needs anyway. I tend to blame it all on Bill Gates, who became way too rich by over engineering Microsoft programs, but I'm sure others contributed to this modern trend as well.
I'll stop now before entering full rant mode. I guess I'm just an old malcontent who's reached the age where I hate change. (I blame Bill Gates on the modern trend of 'planned obsolescence' too…)
