Bought an SH-201 from George a few months back and have just started using it live last week.
Use it on top of an MS-60 or my B-3, with a GW-7 or Rhodes on my right hand. Really don't know what I'm doing with it yet, but really like the build quality, price and potential.
George tells me it is appropriate for a top synth in real time.
I'll let you know..
