Simple minor tacking is what I do just like Cybercow said. Whether using an on-board pot or actually in my case I tack a wired pot. Easy to remove without filling the pot pad hole. I also found you can use a cut piece of a cheap IC socket and use just one side (not the more expensive tooled one) and use that as a socket to push the Reverb Brick right in there and it will fit snugly. I would not suggest that as a permanent solution but it does work well.
