Based on hearing a few shows of the Stadium Arcadium tour, I started thinking that the EHX Holy Grail Reverb was plugged only into the Silver Jubilee - a cable would go straight out of the CE-1 into the Major, and another one passed through the Holy Grail (who had a red tape glued on the output) and then went to the Silver Jubilee (who was also marked with a red tape). Do you remember if that was what happened? And if so, how did you get to have the reverb only coming out on the left side?
Dave Lee: "Now that you mention it, I seem to remember Dave Rat (for a time) only wanting the reverb on one side, so he could control it in the mix. So yes. There was a period were that was the case."
