Bernard,

I don't have it yet. It is in the mail. I used the SD2 and switched to the SD4, as I was able to use a MIDI guitar with the SD4. I've since sold the MIDI guitar, so I thought I would "upgrade" to the SD1000. I'll let you know how it goes.

I also have the SD4 for sale if anyone is interested. I think Ketron products are very good.
