frankieve and DonM...thank you for your contributions to my post. Would you believe that I checked my email just before going out the door to drive up to see the SD5 and the other products and caught your postings. I knew nothing about Ketron and your comments helped me to understand the product and the company. I had an awesome experience playing the SD1...didn't get to touch the SD5. That's an incredible sound and I've been playing many, many years. I'm going to post a new topic requesting more info on Ketron as I'm going to buy one but need as much feedback as I can get because this is a whole new animal for me. Please contribute to the new topic if you have more to add.
