Pat,
I’m sorry for the late response. I just got back in town from the holiday weekend.
You are on the right track with adjusting the tone trim pots in order to get the depth “deeper”. You’ll need to put the pedal in calibration mode to adjust the individual sides (high and low) separately in order to adjust their depth to the maximum setting. Keep the depth pot at max and set the phase switch to “in” while you do this. You may want to start by turning up the high trim pot all the way and then turn up the low trim pot to (tonally) match it….or vice versa.
Remember the suggested 5K trim pot value was only a starting point to ensure the pedal works. The final adjustment (and tonal balance between sides) is done with your ears…so there is no need to use your meter to re-measure the test points.
