    What is the difference between the Gallien Krueger 1001 RB model and the newer 1001 RBII models? :confused:

    Wasn't the 1001rb only 540w at 4ohms? The rbII is 700w at 4 ohms. I'm pretty sure. Not 100%

    The II series had some circuit redesigns, although I don't know exactly what, that were to address wome reliability issue as well as up the power. I don't know the specifics, just that some of the old ones went up in smoke. I would assume one that is around and working today wouldn't be a problem amp of it's lasted this long. The series 2's are some of the most reliable things out there. That would be the 1001RB II and the 700RB II.

    Actually, I think the first runs were the 1000RB, later changed to the 1001.

    The 700RB kept the same model number and just added the "II" to it.

    Thank you. Exactly what I needed to know before I buy a GK used amp head.

    Not much, in terms of tone. I owned both a first generation 1001rb and a 1001rb-II for a while until I decided to let the older one go after it'd performed flawlessly for me for over a decade. Just didn't need both.

    I think the "slight redesign and more power" is correct. You could ask this in the GK mega thread and hit more people who might know.
    If you want/like a grittier tone, the 700 might be a better choice...the 1001 stays cleaner longer because more headroom, which is my preference. Either can be crazy loud.
