The SE+ upgrade seems quite intriguing yet the price of it is rather off putting to me. I purchased my Line 3 new and have never had any additions or changes made to the piece. I am wondering if simply replacing all of the tubes would be a viable and economical approach to improved quietness and more authoritative bass. And, I do marvel that Chris doesn't appear to have any challengers in so far as offering the upgrades. Any comments from the members would be appreciated. Thanks!
