Why does the reverb stop abruptly on the Hall of Fame Mini when I press the switch?
The reason this happens is because the Hall of Fame Mini pedal is a true bypass pedal. When you press the switch it completely bypasses the pedal including all outputted sound that is currently play. They result is an abrupt stop.
The only way to solve this is to let the pedal finish is cycle before turning it off, or to look at our of our pedals that offer a buffered output like the Hall of fame, Arena or trinity Reverb pedals.
