I’ve been trying to optimize my Quaverato’s internal high, low, and gain trim pot settings to minimize noise and set the best tone for my tastes/purposes. I bought my kit and downloaded the owner’s manual and assembly instruction .pdf’s some time ago. After building it, it worked, but was a bit noisy, at least with my single-coil guitars.
When I opened the case up some months after completing the build I reviewed the owner’s manual and assembly instruction .pdf’s and found that there appears to be a discrepancy between these two documents in regards to the gain trim pot. The owner’s manual says on page 13: “Turning this pot clockwise increases the gain, counterclockwise decreases the gain.” The assembly manual on the other hand says on page 44: “the volume output of the pedal should be roughly the same when the effect is bypassed or engaged [with the volume knob at 12:00]. If not, adjust the GAIN trim pot (VR10) until it is. Counterclockwise gives more gain, clockwise gives less gain.” The instructions for the high and low trim pots that I found on page 45 of the assembly manual state: “If you would like the tone to be a little brighter then turn up the HIGH trim pot (clockwise) and turn down the LOW trim pot (counterclockwise). If you would like the tone to be a bit darker do the opposite: turn down the HIGH trim pot (counterclockwise) and turn up the LOW trim pot (clockwise).”
To tell the truth, turning the screw on the trim pots doesn’t really seem to do a great deal to change the gain with the gain trim pot or tone with the low and high trim pots. They don’t seem to have any stops, and the changes seem almost imperceptible. If rotating the screw on the gain trim pot counterclockwise increases gain, I would have thought that the same applies to the high and low trim pots, I gather this is incorrect, and that to increase the high or low end tone with the high and low trim pots requires turning the screws clockwise?
Frankly I’m a bit confused about making the adjustments. I don’t really want to desolder the jumpers to reset the resistance with my meter according to the assembly instructions, but I guess it might be smart to do that and start over from the recommended baseline.
