Peter posted more details on the noise floor issue. Not exciting.
8 - The charge pump in the SPS system has a small voltage trimpot, but I've found that this trimpot also has a significant impact on the noise floor. I'm still investigating exactly why, but there are settings that are "sweet spots" that significantly reduce the noise floor, as well as other spots that induce a significant amount of noise. I plan to make a video on this later, but here is a process on how to reduce the noise floor of your pedal.
STEP 1 - Connect your pedal into the signal chain as you typically would have it, but turn it over and remove the backplate.
STEP 2 - Connect your instrument & turn on your amp, but completely turn down the volume of the instrument (or whatever is last in the chain before the pedal)
STEP 3 - Activate the pedal and then turn up everything to maximize the self-noise of the pedal.
STEP 4 - Find a small screwdriver that can turn the tiny voltage trimpot (I use a flat head screwdriver that is just 1.5mm wide).
STEP 5 - Make really tiny adjustments to find a "sweet spot" where the noise floor drops considerably (in my tests, most were around 3:00).
STEP 5, part II - If you are connected to an output rated for 100mA, you may need to set the voltage somewhere between 12:00 and 2:00.
STEP 6 - Please report to me what you found, including the power supply you were using.
I've started making this process a standard part of my testing procedure for every pedal, but I don't know if what I do with my power supply (1 Spot) will exactly match your setup. I highly recommend this procedure for everyone. I should also note that some of the "sweet spots" took some time to find, but the big drop in the noise floor was well worth the effort. If you can report back
