I've been trying to find a way to control the overall volume of my Q for some time, and I think I may have have found how to do so last night. Did anyone else know that there is a small trim pot inside the Q? Neither did I! It's adjustable from either side of the circuit board, so you don't have to tear it apart to get to it. As far as I can tell, it's not a volume adjust, it more of a frequency adjust. Basically, you can run the Q in Boost mode, which allows the Gain knob to control volume, and you can adjust the internal trim pot to get the sound you want. Simple enough. Have fun!
