While we were not very familiar with Sumo, we found this Aurora Tuner to be quite capable. The FM easily pulled in many stations and sounded wonderful in the process. The unit is in very good condition physically, with some small scratches and scuff marks here and there. All switches and knobs were cleaned and lubricated and the unit is in excellent working order. Some of the lettering seems to have come off the back panel of the unit, but that has no effect on performance.
