At the start my english is bad and im an amateur playing piano. But i have played Yamaha dgx-670 now for a year. Before that i had Yamaha PSR e373... When i played that psr...i had very hard time to play acoustic piano after that. Now when i have playing that dgx-670, all acoustic pianos what i had been playing including Yamaha c5 and very demanding Finnish piano Fazer..... Im very sure that ghs action is very good for beginners. I was reading this Forum and i noticed that everybody was barking that ghs action. Thst action is so bad that it IS useless...So for beginner, ghs action on my opinion is edequate for playing real piano...

Ghs is perfectly fine.

I think it is quite playable.

I don't have an estimate on the number of ghs 'action' pianos ever sold, and I'm assuming the actual total number is significant.

The learning of playing piano, and how people start, and what they started with ... is part of the special story in human history. So many different paths and approaches.

Real pianos include acoustic pianos and digital pianos. Back in the early days, there was actually no other choice but to realise pianos in the form of the full mechanical type. It is later, when electronics and materials, and computing/computer technology plus other advances and contributions from people, where other sorts of pianos became realised, developed, created.

To me .... somebody starting with the most inexpensive piano, or organ, even battery operated etc, and getting into music, and keyboard playing is incredibly nice, and special. Each person has their own 'journey' ..... in music, and in pretty much anything.

Transitioning between instruments is part of the fun and experience. When hopping on an acoustic grand piano for instance (switching from digital to acoustic and vice versa), the user needs to adjust or make some adjustments ... eg. pedalling adjustments etc. All part of adjusting and adapting, which people are certainly capable of doing.

GHS is good. Until you play something better. GH wasn't better, it was worse, imo of course, and many acoustic uprights didn't measure up either.
But plenty of others do, and are more convenient for playing into those notes, like you sometimes have to.

My experience is that "GHS" action isn't the same across keyboards, even on the same model - my local store has 2x P125s and a P45, and the P45 feels way better than either P125, but both of the P125's feel different to each other.

I'm hesitant to just refer to "GHS" action as anything that's supposed to be meaningful, because of how different it can feel across different products and even the same products.

I've played other "GHS" actions in the past too, the above are just the most recent comparison - I've had this "issue" every time.

But, I don't think it IS an issue, btw. I think it's no different to guitars - you need to play the individual instruments and decide what feels right for you. The reality is you might prefer one P125 over another P125 because the keybed feels better on one than the other.


EDIT: I forgot - the store also has a Yamaha DGX-670 that I compared, and that keybed was way better than the P45 and P125 - it was nice enough that I was considering picking it up, really liked it. It's also.. "GHS" again. LOL.

I wouldn't recommend either P125's action. I thought the P45 felt great. I thought the DGX-670 felt fantastic.
All "GHS" actions.

There's a KORG B2 in that felt better than the P45 and P125s, but about equal to the DGX-670.


Buying based on specs seems a bit silly, really.

Yes -- going from a PSR (synth action) to an acoustic piano is a shock!

The GHS action is much closer to an acoustic piano, than _any_ synth action.

Good luck with the DGX-670, it's a nice DP.

I had a similar experience... played a MODX8 and DGX660 next to each other at a store... if the MODX8 had felt as good as the DGX, I'd have bought the MODX8. But it didn't feel nearly as good. I did end up buying a MODX7. But if the MODX8 felt better, considering what I was doing at the time, it's not inconceivable that I could have ended up buying the 7 and the 8. if the 8 had felt like one of the "better" GHS implementations.

The ghs action is better than an old unregulated acoustic piano.

Ok. Thaks for your answers. I think that i choose right dp piano for me on that price category... I played before that dgx purchase, old Yamaha p115, which was played many many years at church hall...It was feeling like very sloppy and had some clearance on keybed. I think that piano was not having any maintenance. I was very surprised that dgx-670 was feeling so different... btw when i was reading some stories in the internet about that ghs action. I was wondering that why would Yamaha do years after years same action which is not good?

Hard to say. Whenever there are negative comments about something like a 'key action', there are usually also a significant number of positive ones, which offsets the negative ones. So it's going to be the usual thing in life ...... make a choice or choices (where possible).

Yamaha hat quite inconsistent keybed across their range to my experience, despite sharing the same name, I believe they share the same core construction but yamaha just silently modified the GHS/GH/GH3 overtime and across the range, I noticed it too between different GHS from different Yamaha pianos, my friend also said that the NW keybed on the CP4 he once own feels noticebly better than that of a CLP470, or a NWX of a CLP545.
The GHS imo is perfectly playable and well designed, but it has a very short pivot and that's what I/and most other feel negative about it
