Hi Donny,
true. You didn’t like the sound of sx as much as you liked the sound of psr950/970
I suppose that comes under the heading of Listening? in which case why isn’t it possible that Don thinks he can hear a sound improvement on theVH2 harmoniser.

I don’t sing so never used a harmoniser.

I personally believe my sx900 sounded better than my S950, had them side by side for a week.
I definitely believe my PA4X sounded better than my PA3X.
That relates to what I hear. Some may agree some may not. It’s subjective.

Functions on the other hand are not. One either has to compromise and find a work around, or give it a miss.

For you the SX obviously wasn’t a good fit. When does your Roland arrive?
