Intouch,
Will try that. Thanks. I wish the dealer would have suggested this. It is amazing , though, the major volume output difference that occurs. Have not measured it but , something in the area of 80db to over 120+ db ( much louder than my chainsaw)change. Even louder that the Lindsey Buckingham concert I was at last night---- and that was loud,,,and good.
have a good one,
