I've experienced the same issue as you. A big resistor as a "pull down" would not fix the problem (eg. 1M, 2M2, etc). The POP is in other TBP pedals after de buffer, a LOUD pop.
What I did?
Simply put a SMALL resistor as the same way you put a "pull down" one, In my case, a 1K resistor fixed my problem. No more pops in my TBP pedals. The thing is that you don't want to keep the capacitor charged all the time, so a small flux of electrons must find a way down to ground. The Small resistor does it.
You could try a Pot, e. 10K, wired as a variable resistor to ground and find the sweet spot (in order to keep the output impedance low). When your other pedals stop popping, set the resistance and replace it with a fixed one. If you don't want to do that, just put a 1K in that place.
Tell us your results.

With a 10k resistor, you're screwing up the input impedance of the next effect.

sounds like you might have an LED problem. i know it's written up on the AMZ site. you can find it on this page-

Haven't tried TBP pedals after it yet but I am pretty confident the popping will be reduced as well. This Super Buffer is impressive. I did some extrme tests such as using two long and crappy cables joined just with non shielded wire, even touching the "live" tip of the junction with my hand, and NO LOSS/NO NOISE at all. Impressive!!!
