Well, I finally got my rig together. Ampeg 4x8, and hartke 410XL, with a GK 1001 head on top. Sanamp out in front with the P bass. I have just one word to describe the awesomeness of it: Earthquake. It was just the most thundering monster ever. Punch to knock out a giant, and low end to rattle anything within the neighborhood. I think I have my perfect rig. It's the first real test, and it passed with flying colours. My drummer has always been proud to say that he has always been louser than me, but not tonight, my low end friends. His decibel record has been shattered. I want to buy an SPL meter and see where I am at... This oughtta be fun. And yes, I did wear ear plugs. And suprisingly, no cops showed up.
