i own holy grail plus for months now and i am unsure if my unit has a problem, i had been using the boss psa adapter to power the unit and i wait a couple of seconds (around 6-8 seconds) before the unit powers up on/off, i have their cathedral reverb unit too which is a more powerful pedal but only takes maybe 1-2 sec to power up, does anyone have same problem? is this normal, thanks
