Tuner unusable

Just to be a little more clear. I have been a pro musician with 25 years experience with guitar tuners. Am also a guitar and amp tech, and luthier. So I am not saying this about the QC tuner lightly or out of ignorance.
It is less reliable than every other tuner I use. It ‘can be’ accurate. But it takes twice as long to tune a guitar with the QC than it does every other tuner. Even iPhone app tuners.
It is not ideal for on stage quick tuning.
Given the price point of this unit, and it’s potential with processing power, I believe the tuner desperately needs help.
It is literally the only major thing I do not like about the unit.


I experience the same. I am much quicker tuning my guitar per ear than with the QC, which is surely no option at a gig. The cursor constantly floats around, and the only way how to deal with this is constantly hitting the string so the cursor has “no time” to move around. Any cheap Polytune pedal does a better job. I dearly hope NDSP will fix this very poor execution of a tuner…

On bass I have the other problem it takes time before the cursor settles (1-2 sec) but then it is stable. I tune to the stable point and it agrees well with my other tuners although takes a bit longer time.

for me as an hobbyist it is not a major problem but it can for sure be improved.

I have found the tuner to be accurate but it does seem to move around too much. I guess this could lead to longer tuning, but haven’t really noticed that… maybe a update could give it some stability.

I’ve found the tuner jumps around a fair bit and takes me longer than other tuners I have used such as polytune. I also have issues where on low tunings like low a 7 string tuned down to A, it seems the tuner picks up that the ‘initial’ pick produces the correct tune rather than the note that is ‘hanging’ which drops down a few cents. This makes it tricky to tune low notes.

I’ve tested the QC tuner against a Peterson StroboStomp2.
As the StroboStomp2 display features 4 strobe bands which represent different groups of octaves the display is “always” moving and with a stringinstrument/quitar it is kind of an approximation to the state stable - if it is stable then only for a short time. Nevertheless it is super-accurate and if you’re used to it, easy and fast to read.
I’m mentioning this because in my opinion it is the same with the QC tuner:
Here while comparing both tuners the QC tuner is showing exactly the same as the Perterson tuner tendencies included and no lag - which is great! , but the QC tuner is also moving like the Peterson.
Maybe it is as “raw” as a strobe tuner and there is no flattening/smoothing as it is happening with other tuners I guess.


It’s not as responsive as my Polytune3, but it’s also not the worst I’ve ever used. Amplitube’s tuner might be the least responsive I’ve tried.

What I find interesting is my pro musician friend, who has Kemper, was here playing either the QC and the first thing he said was nice tuner. I am not trying to lessen peoples issues. I have had AXFX Helix, and now the Quad Cortex. It seems like no matter what the unit is there are those that hate or live he tuner. Even after a huge tuner upgrade in the Helix that added three modes for people to choose from there are still complaints. And background shouldn’t enter in. I have dropped background issue to try to get my point across but have recently realized no one cares. They only care about their issue or non issue.

Ok. Enough of that. I agree something changed with 1.1 on the tuner. Good or bad? I am not really sure. I did check it with my Peterson and it’s accurate, but if you let it ring too long it does drift now. It did not seem to do it for me before. It seems to me it is currently reacting like an old needle tuner and the moment.

Yeah, that seems to be a tough one in terms of people’s tastes. My friend always hated the AX8’s tuner. Worked fine for me. QC feels pretty much the same, meaning I have no problems with it. If it starts bouncing, I pick closer to the bridge. Not trying to dismiss the OP’s issue…I probably just have a crappy ear LOL

I second this. I thought it was me or my evertune bridge being funky but when compared to Logic’s tuner it became glaringly obvious. This tuner is really unreliable and has been for a while. Pretty unpatient for the next update tbh…

I’ve seen the same weirdness with tuners. Sometimes the tuner would work on a guitar and on a different guitar it wouldn’t.

In my experience one culprit that will make a sensitive tuner wander is the guitar pickups being too close to the strings. The magnetic coil interferes with the natural vibration of the string. If it’s way too close this will cause the sustain of the guitar to be very poor.

I have an Ibanez SV5470F-NB that suffered from the same symptom. I bought this guitar in near mint condition but the setup was a disaster so I knew the prior owner had been tinkering. I corrected the setup, had the guitar Plek’d and lowered the pickups.

It sings now, no buzz, lowest action and softest touch I’ve ever experienced on a guitar AND the tuner stopped misbehaving.

Just a thought.

I would love to have the ability to select the muted output(s) when using the tuner.
As I plug the vocal microphone and the guitar in the QC, I would need to tune while leaving the microphone opened, and as long as this won’t be possible, I will have to keep on using an external tuner.

Is there any progress regarding the tuner? For me it’s still unusable with OS 1.3.2 compared to my Peterson or Axe FX3 Tuner.

@docsoul - Hey there have been several improvements to the tuner since the last discussion with this post. We haven’t received any reports that users are having issues. Please send the support team an email so they can troubleshoot if you’re having issues. support@neuraldsp.com

At the risk of being contrary…

I only just got my QC so I don’t know about previous versions but the latest firmware (1.3.0) has to be the nicest tuner I’ve used in 35 years of playing guitar.

No settling period, stable throughout and accurate to a hair.

Not to mention the huge chunky display! :smiley:


Agreed, I was using my Peterson Strob HD and the QC tuner is just as accurate now.

What bothers me most is the super long press. I really don’t want to sit there between songs trying to hold a button down with my boot (with heels) and wait for it to change over. We need an option to enable an instant switch instead of holding it

I also asked for the feature and this was the reply:
“I don’t think this is a popular opinion, I don’t get why pressing-and-hold the tuner button makes the unit “unusable” in a live situation. Anyway, thanks for the feedback!”

Post the feature and let people vote on it. But for me, 2 seconds to hold the tuner (with or without mute) is not an issue

WIll do this - it’s awkward for me because I don’t actually know if I’m even physically pushing the button if wearing boots and waiting to find out when there may only be a few seconds between songs it’s not a state I want to be in. In addition, having an instant mute is extremely useful

It’s not unusable by any stretch but It seems like a pretty reasonable request given that plenty of people (such as myself) have no use for a tap tempo but plenty of use for a tuner

Edit: I created a feature request:
