I have not gone out with this rig yet. I am rehearsing with a band now and am probably several months away from a gig.
Right now, I am amplifying the signal with a powered JBL monitor (a two-way, bi-amped monitor with about 140 watts total). I can also run a line out of a direct box and feed the house PA if there is a house PA. I am hoping to be able to go through the house PA in many instances to save me carrying equipment. But sometimes the sound systems are bad and it may make sense to at least monitor myself with the JBL. Time will tell.
What is a cathedral pedal? I never heard of that.
