Using your EVH 5150 III 100S 4x12 Guitar Speaker Cabinet is easy. First, connect your guitar amplifier to the 1/4' speaker jack. Make sure the connections are secure. When moving the cabinet, use the recessed side - mounted steel bar handles and the EVH casters for easy transport. For best performance, keep the cabinet in a dry and cool place. Avoid exposing it to extreme temperatures or humidity. To clean the cabinet, use a soft, dry cloth to wipe the black textured vinyl covering and the perforated steel grille cloth. Don't use harsh chemicals or abrasive materials. Periodically check the speaker connections and the overall condition of the cabinet to ensure everything is in good working order.
