D'Addario Tuner

June 10, 2021, 1:52 PM · I purchased one of these when my Snark tuner started failing on me (not a battery issue), but neither I nor my teacher can open the battery compartment to remove the tape which will allow the tuner to be turned on. Has anyone else had this issue? I hate to try and pry it open with a knife...

(I have replaced batteries in them before, but out of curiosity I just opened one and this one at least wasn’t easy. I had to sort of put a thumbnail under the edge and pry on it. A small screwdriver might be easier?)

What size battery does it take ? Even the packaging does not say ( I found a photo online). I see that it will stay on for 10 minutes before turning itself off. Is that correct ?

I have been using a guitar tuner which clips onto the scroll and it is always in danger of falling off or making a vibrating noise as it touches the pegs.

I don't know how long it will stay on because I always turn mine off as soon as I finish checking my tuning. However, there are times I have left it mounted on the instrument while playing if I anticipate needing future string intonation checks while the noisy (orchestral) environment continues.

But I would never leave the device "on" electrically because those little batteries run out of energy pretty fast.

The same tuning device is also sold in a different clamping mechanism that holds it on a cello bridge - that works just as well. I have tried some other devices that clip on the violin scroll, but I like this one most. Only problem with it, it tends to make one a "lazy tuner" and when I can hear myself I always finish the job by "checking the "fifths."

June 12, 2021, 8:14 AM · I trimmed the rubber feet on one of these to fit one of my violas - and it worked. The normal spacing was a tinny bit too narrow. An unaltered d'Addario will just fit my other, slightly thinner, viola; so that's all I need in my double (violin/viola) case.
Edited: June 12, 2021, 2:23 PM · What I didn't anticipate, is mounting it on the body means it's a bit close for my "music stand glasses", but that's ok. I see it well enough for my needs, which lasts about 3 seconds at the start of a practice session.
