    Picked this up off of local craigslist. Assuming it's March 1985 production? Series I right? GK aficionados let me know please. In very good shape for its age and sounds awesome. Very happy!

    Congrats! Does it power the Neos well?

    I have an '87 400RB that looks identical except the back panel is black.

    IIRC the very first 400RBs released had 2 input jacks instead of the single input with -10dB switch.

    March 85 it is. I have an '84 and an '88. Crazy reliable and still sound great. To really open her up, get a 4 ohm load on it. 8's okay, but it's great at 4.

    I'm not sure about production date, but I believe the first version did not have a detachable power cord and if I'm not mistaken, the boost only can be turned on by a foot switch.

    Your amp does look clean though!
    Enjoy!

    Good to know. Only played it through the top cab in the pic so far but plan on knocking down to 4 ohm in most cases with both cabs.

    Weird thing is the boost on this one is engaged without a foot switch connected. Gonna connect a foot switch and see if I can shut it off that way.

    At 8 ohms it is 130 watts rms. 4 o load will give you the full 200 watt output .

    A 400RB with dual inputs? .. could you be thinking of the earlier 400B?

    It'll stay on or off depending on how it was last set via the footswitch. Boost on is the way to go ;)

    Yes series one. Footswitch allows you to turn off the boost. Nice find!
     
  16. I've been thinking about a 400rb myself. At 4 ohms is it powerful enough for a live setting? I don't have any experience with them.

    If you have speaker area yes. I would not try with a 110 or 112 cab, even a 210 or 115 might be a stretch depending on your bandmates.

    It's quite capable,and most will tell you,a very loud 200 watts. I've been gigging mine(born Jan.'85;)) in bar bands forever without a single problem ever. Built like a tank,and the famed GK growl at any volume.

    I'll be the first to admit,we're pretty loud..and I use a single 4ohm 2-10 cab quite often with the 400..nooo problem!;)

    Enjoy ! Great, great amp :)

    They are pretty loud with the right cab. I gig mine no problem with a relatively loud band and no PA support.
