    Hey all I recently picked up a used GK 400rb it looked rough but played great and I got a smoking deal on it. The outside metal case was rough, solved that by taking it apart and painting it with krylon texture paint....looks just like new. It also is missing one knob and almost all of the gray inserts. Anyonne have any idea of what I can do to replace the knobs? I thought about getting some marshall type knobs with set screws or are all knobs threaded the same? Any ideas?

    Most good electronic supply stores will plenty of different knobs that will work. Or just call GK customer service if you want original.

    My old beat-to-death 400RB has the original knobs but if they fell off, I'd go to radio shack and get some. Part of the charm is the scratches, dents and broken handle from gig after gig after gig... No one "relic'ed" my friggin' backup amp - it just got USED.

    400RB's are supposed to get beat up. Used and abused they are pretty good work horses.

    Do what I do - stick in pieces of plastic cut from milk bottles/yogurt containers. mark with a Sharpie. Move on from there. Your amp will still be working. No one can see and no one will care.

    Are the 400rb knob caps that you're looking for the same as the ones on an 800rb?

    I'm missing the grey inserts on two of my knobs... Given its overall condition, it matters not.

    Now, were I trying to sell it...

    The guy at SamAsh by me was able to look it up and order it, real cheap. Knobs and inserts sold separately.

    Anyone have just ONE knob and a cap or 2 knobs for the Old Old type 400RB/800RB?
    (The type on the right)

    Wow this would help me out!

  16. Many years back, when I first got mine, I called G-K to ask about buying a couple of inserts.
    Before i finish asking, the lady on the other end interupted me with "Yeah we know, they fall out. How many do you need and where do we ship them".
    Great customer service.
    No charge!

    Unfortunatly, I have heard they ran out of them.

    I expect there are many knobs that will fir.
    Some may even look close.
    If you buy a full set to have them match, save the old ones for those needing one or two.
