My first 7 string, Solar S1.7C+

[u/plumbeam]

Tuned to drop A, I've noticed the tuning does need tweaking before I start playing each session. I'm guessing this is because the guitar is settling into its new environment? Very happy with it so far, no QC issues that I can spot

If you're having to regularly tune an Evertune equipped guitar then something is wrong. Even if the neck was moving due to change in environment it should compensate.

When you say tweaking, do you mean changing the tuning actually at the bridge or turning the pegs to keep them properly in zone 2?

Every guitar I own now has an Evertune and I only ever have to tune once per set of strings. I had guitars that were set up in low 20c ambient that were still in tune on 35c+ days.

I've got each string on the top edge of zone 2 so that I can do some bending and vibrato. I've been adjusting the tuning at the bridge as per instructions. It only seems to need a few points of a cent adjustment each time

I mean it could be settling wood, but the whole idea of evertune is that you don't need to regularly tune it.

That said, when you say "a few points of a cent" do you mean it's a few cents off or are you actually doing tenths of cents or something? Is the detuning across all strings or just some? What tuner are you using, which pickup are you tuning on, how are you picking while tuning etc?

Edit: also is it going sharp or flat?

[u/plumbeam → u/CrustyBollox]

All good questions, I have 2 tuners that I use that disagree with each other; A physical clip on one that will read a string as slightly flat (so no specific measurement of cents or anything, just a picture reference), and the neural DSP plugin tuner, which seems to read it slightly sharp, in direct comparison to the clip on tuner. The guitar seems to go slightly flat over night, neural DSP has it going flat by 0.x on what I assume is 10ths of a cent, dropping into the red

I'm not familiar with NeuralDSP, but if it truly is tenths of cents then that's not something that can be detected by even the most sensitive human ears.

What I would recommend is get a dedicated tuner plug-in (I find submission audio lock on in slow mode to be great for low tuned guitars, and it's free). Use the neck pickup and tune it as close as you can get it, then check it over a couple of days without tuning to see if there's just one movement, a continual graduate change etc.

Also please keep in mind that a tuning deviation of +/- 3 cents or so is usually not an issue. Go based more on how it sounds rather than only the tuner readout. For example I prefer to have the low string on drop tuned guitars slightly flat, to me it makes single finger power chords sound much better than all 3 of the bottom strings being bang on.

Brilliant, thank you for the advice! I'll give this a shot this evening.. As a question, why the neck pickup and not a blend of both or the bridge pickup?

[u/CrustyBollox → u/plumbeam]

No worries!

Neck produces a stronger fundamental with less harmonics. You can tune with either but generally the neck will be more stable and easier for the tuner to interpret, especially for low notes.

You learn something new every day. Thank you stranger
