I finally got around to buying and installing the cap. Your install pointers helped me to find the correct pins Brach, the square pad on number 1 makes it pretty straightforward to count down to pins 7 & 8 on the correct side and orient the cap in correct polarity. I used hot glue to firmly mount it as recommended. I think the cap does quiet the Quaverato down some. I haven’t tried it with my other amps, but it still makes some (tolerable) noise with my old Peavey Bravo, more on the drive channel, but I think it’s quieter when it’s in bypass now. Battery power quiets it down even more, but as you point out, the Quaverato draws considerable power (I guess because of the light dependent resistor (LDR) and light emitting diode (LED) optocouplers?). If you use a battery with an external connector, be aware that the tremolo effect may die before the indicator LED’s when the battery is dying. This threw me off, I kept turning the depth up till I had it on max, but eventually I couldn’t hear any warble, and I thought my cap install might’ve killed the Quaverato before I had the sense to try powering it with a plug-in power supply transformer. It came back to life and realized that I’d just killed the 9V battery, not the pedal.
