I picked this 4004Ci up off of Ebay this week. I've been wanting one since I got my 4004LK several months ago. It has low action and plays effortlessly. Tone wise it has the traditional Ric tone with a little more lowend. Just perfect. It sounds very similiar to the LK which is a great. Unfortunately there is also a "bad" . My Bartolini equipped 4003's sound pretty thin in comparison.......so I don't feel much of a need to hang on to them any longer. I have also grown to appreciate the oiled finish and non-painted neck/fretboard of the 4004's. I'm going to thin the herd (hello evilbay) and just keep the LK, Ci and 4003s8. I just can't part with the s8....it is a joy to play and sounds so unique/huge.
