"That is right. You can believe your eyes. This is a fully functional Rhodes Chroma Expander. I have never seen one for sale on eBay or anywhere else over the last few years. I would dare say that this may be one of the few chances you will ever have to own one. This Rhodes Chroma Expander, serial #0110, has been completely painstakingly restored internally over the last 3 1/2 years at Three Wave Music. Prior to that, additional restoration work was done by David Wilson at the Synth Museum in New Hampshire. You will want to refinish the wood to bring it back to its former glory as the outside is not where you will want it to be. There are also a couple of small spots where the front panel membrane is slightly lifted but it does not interfere in any way with performance of the unit. Three Wave Music secured it and made sure it was stable.
It is interesting to watch the interest in Arp 2600s.
