using the vero layout for the orange treble/bass booster, where would I put the 1M resistor to stop poping?

from BLEND2 (the middle lug of the pot) to ground.

I think the blend pot will act like a pull down resistor so you don't need to add one.

  The blend pot has a cap between it and ground.
  Pulldown at the wiper @ say 1m + whatever resistances to the outside lugs [depending on how the pot is set] should allow enough current to drain both caps to prevent popping.
  a pulldown to lugs 1 or 3...would give 1 meg path to ground on one side, ~1.5 meg to the other [through the 1meg + the 500k of the pot]

  Funny question I thought of when typing..
  Would a larger cap causing switch noise cause a POP, in comparison to a Small Value cap making a 'pip'...smaller more HF popping noise?
