Hi Guys, thanks for the reply's. I had no intension of running my amp at 2 ohms, was just curious as I had read on line and here that the Bassman 400 Pro,(white face) head could be run at 2 ohms as I have the (black face) head. From what I could gather they both seem to be the same head, they both have the same controls and specs (Fender owners manuals) and only seem to be cosmetically different. I do like the amp as it has enough power for what I do and was considering using a different speaker setup. Currently running a Hartke 4x10 @ 8ohms but it's becoming too heavy to move and wanted something a little lighter. Was thinking about the new Fender Rumble cabs or the GK CX series, a 2x10 and a 1x15 @ 8ohm each to get the 4ohms and 350 watts it has, more power is always better, any thoughts on them or other suggestions. Thanks.
