I use to have the Ampeg rig. Was the best bass sound I ever had - trouser flappingly loud and acres of headroom. Loved it even though was only doing the pub circuit. BUT - was huge. Wouldn't fit in my car so had to always keep it in storage then in band van. I could barely move it myself. Eventually, after it had lived in my dining room for a few weeks, my missis insisted I shift it. Now on Orange Bass Terror and SP212 - sound ace, tiny, lives in the boot of my car. Happy wife! Happy back!
They are blood ace though Andy
