These are marked as DX5 (F) and DX5 (R). I'm assuming that means front and rear. I got these but decided to stick with EMGs. These are used, in VGC, with just a little logo wear and string wear on the front pickup. Rear pickup is in better condition, with no string or logo wear. Dimensions are 4 1/4" long, 1 1/2 wide and 3/4" high, similar in size to the EMG 40-J I have for sale. Thanks for looking.
