MV50 Clean with Fat/Bright mod installed by myself, and a BC108 (speaker unit replaced with a Jensen). It's currently working without any problems. Also, the effect of the modification is difficult for me to distinguish, and the finish is rough due to amateur workmanship, so please purchase only if you understand this. One of the rubber feet on the bottom is missing. Belden speaker cable and power cable are included. There is no original box or instruction manual.
