Yes it is a trim pot and you can turning for increasing or decreasing , so what is to use for ? how do you known it is BAD or GOOD ?
I had a smith once and don't remember there being a trim pot. but that's not to say one wasn't there. it's been a few years. I'm going to guess that it's an output trim for the active preamp. some people like their active and passive volume to be really close. I didn't really worry about it. I would only adjust it down if the bass is distorting the preamp on your amp. I would only adjust it up if the bass were not putting out comparable output to my other basses. as will said, your ears will tell you if you did something wrong.
