Hello all of you that have the SFM, I was wondering if you guys mess with the trim pots inside and if you all have found a setting that works well. If you do would you mind sharing, It seems the left trim pot works for the overall blend and the right pot works with how wet you want the filter to be. I'm trying to find a setting that works well with my passive jazz bass and a class D amp, also a setting that works in both lowpass and bandpass. Maybe I just need the original factory setting as I bought it used. Also the left pot just spins free while the right one does stop after a certain point. Im not sure how one would describe the settings without pics but maybe we can figure that out later if I hopefully get some participation in this thread.
