I got a little story for you all!
Over the summer I bought another 410 cab to go with my existing one. My brother is the lead singer, songwriter, and guitarist in my band, and he was rather upset that I bought another cab, because it takes up even more space in van.
Well, over the weekend he was dabbling with my rig (which I am okay with) and he commented that my rig seemed to be acting a little off. He commented how it was quieter and it just lacked that fill sound. For THIS rehearsal, I had both cabs stacked, but only one plugged into my amp, but he didn't realize this. So I plugged in both for him.
He played again and said, "WOW. Yeah, I am glad you bought the other one. That sounds REALLY good."
And then I found $5.00!
It's a lame story, but I thought you all might appreciate it!

It made me feel good.
