It made mine significantly louder. I put it back where it was. It sounded better. titti Posted 2013-10-05 9:57 AM (#477726 - in reply to #477719) Subject: Re: two questions...the 1° is on the trimmer Joined: January 2011 Posts: 348 Location: Italia, Zianigo di Mirano (Venezia) ..if I understand correctly,the trimmer adjusts the volume of the preamp?

You just caused me to pull-out all of my OP-Pro preamps looking for the little knobby. None of my OP-Pros have that... Although many have a hole in that spot that just shows green circuit board. I do have one on my VIP preamp. But that is the only one. If I had found one I would have definitely experimented with it. I would have liked to have an OP-Pro with a little more volume for playing-on-the-street.
