when I'm using the 3300 course I have the internal sim off , I'm aware of that , I was talking about a certain clarity of tone maybe down in the midrange , to my ears ,for lack of a better term, it lacks a certain amount of body or heft . over headphones , to me , it seems to get a little more heft to it when the sim is disabled ,which one reason why I prefer the vent
when I'm not using a leslie . anyway , thanks for your response , I'm looking forward to the update for sure
