DD-1 this DD-1 that. FUcks sake everyone, as long as he isn't overpowering like crazy, sets it by ear and conservatively, no harm done.
Hell, even an old school o-scope will do the same job as a DD-1
and you know what the problem with this is? your definition of setting it by ear and conservatively is not the same as everyone. While you may be able to do this its not something everyone can do. Its not even something I like doing and ive got a few more years experience than 90 percent of the forum.
