Hi Allan

Welcome to the forum

There is a section on this forum dedicated to PSR  970 keyboards,perhaps you would be better to post your query there.This section is really intended for Genos

Hi all!

I consider this question is general and valid for all yamaha kwyboards that have an  Mic/Guitar Input.
I also have some humming^ground noise and I'm not sure if it is from the guitar or if it is something else.
The mic works fine, though.

To eliminate humming noises, you may want to consider connecting your guitar 1/4 inch unbalanced output to a direct box (with ground lift), which converts unbalanced input to balanced output, then connect the balanced output of the direct box to the mic/guitar input of the PSR-S970.

I tested Radial ProD2 2-channel passive direct box with great results:
https://www.amazon.com/Radial-ProD2-Passive-Channel-Direct/dp/B000B85FV0/ref=sr_1_10?s=musical-instruments&ie=UTF8&qid=1513176842&sr=1-10&keywords=direct+box

If you prefer a single channel direct box, the Radial ProD1 should be a great choice (I did not buy this one, but judging from the superior build and quality of Radial ProD2, I would think that this should be good):
https://www.amazon.com/Radial-Pro-Passive-Direct-Box/dp/B000A8J3N2/ref=sr_1_12?s=musical-instruments&ie=UTF8&qid=1513176842&sr=1-12&keywords=direct+box

Since the balanced output of the above direct boxes is XLR balanced output, you will need a XLR-to-1/4-inch cable to connect to your PSR-S970's mic/guitar input:
https://www.amazon.com/Monoprice-Premier-4inch-16AWG-Plated/dp/B001UJELJ6/ref=sr_1_4?s=musical-instruments&ie=UTF8&qid=1513177488&sr=1-4&keywords=XLR%2Bto%2B1%2F4%2Binch%2Bbalanced%2Bcable&th=1

First connect without pushing in the ground "LIFT" button on the direct box and see if the hums go away.  If hums can still be heard, then push in the ground "LIFT" button on the direct box to get rid of the hums.

Thanks,
Paul
