Bass player friend of mine just got his Aggie S 410 blowout from MF delivered yesterday. Calls me up, "Hey man bring your Walk-About head over & lets scope it out." So I take the head out of the Scout unit, get over to his pad, plug it in, & HOLY MACKEREL, is that fan loud when it's not in the "box". It sounded like one of those gas powered model airplanes was about to take off & fly around the room. Strike 1 Mesa for that one.
