Guitar Exercise 1000 Gen Kondo, Berklee Rittor Music Complete with 2 CDs This item is almost unused. Both the book and CDs are in very good condition. The CDs were only inspected once on a player to check the sound. The price includes the cost of the CD cases, etc., so I cannot offer it at a very low price. I checked the prices on Amazon, etc., and it seems that there is a slight premium value for a beautiful item with two complete CDs.
