I have a Boss GT-6B bass pedal and I am having a problem using a set of ear buds that I recently bought. If I am playing through a pa system and I am muted, I can hear through them fine, but when the system is on, I cannot hear through them any longer. I am plugged in the system through the direct input and I am using the earphone jack for the buds. Is there any way I can use the buds and play through the system at the same time?
