Picked her up on Tuesday. Wheeled her in to practice, and the singer goes " great, just what you need, more speakers". My reply, "that's why they make volume knobs!" So I wheel it next to my old rig. Not wanting to run it full tilt right off the bat, I plug into my old rig, and send a line out to the new one so the speakers get a chance to break in. When the singer says are you playing through both, I tell him I need to break the new speakers in. A good 2 hour rehearsal at a very comfortable volume, he again brings up that's it's overkill to be playing through all that. I gave up on explaining to him what I was doing. So after rehearsal was finished, I decided to really fire her up to see what she can do. OMG!! Hitting the open B, I thought the walls were going to implode! The guitar player comes in from outside and says "wow"! My rig of doom is complete, and I'm in love!!!! If you've never played through a 2x15, you have to try it once!
