    Strange incident at my gig last night......my previously bulletproof GK-400-III cut out in the middle of a gig last night......

    all I got was the red light.......works fine now.......I assume that is was the extremely hot stage that triggered the overheating protect circuit......

    I was running it into an 8ohm 15inch cab and since it was not miked up I was running it at nearly full power (say everything on "7")

    I guess I need more headroom and better cooling

    Thank God I had my Sansamp to run direct!!!!!

    I bought a clamp on fan, around $15, completely silent, 2 speeds. Works great with my non fanned Workingman 300. You might also check out your speaker cord.

    shoot an email to gene@gallien.com and explain your situation. He could probably tell you exactly what it is, though I think you're on the right path.
  4. Do you have it in a rack? And if so is it a 3space rack ?

    bottom space in a rack bag....i'm not sure if it's 3 space, but there is at least as much room left over as is used for the GK.....

    I'm thinking that I somehow had something in the rack bag that covered up the cooling vents or something....or it was just really really hot (I swear I lost 5lbs of water in a 45 minute set)

    regardless...the band (and my wife) want me to get a new amp now, so I guess things worked out ok :D

    hmmmmm....now what?

    1: Need to know what genre of music you play.

    2: Need to know the size of venues you are going to play in the furture. Will all of PA support (prob not)?

    3: How much mula you got to spend?

    I usually don't drive the amp so much, but this gig didn't have good PA support.....

    I play indie rock and we have a loud drummer but the rest of us are not all that loud----Rhodes Piano (through the PA) and guitar through a Fender HotRod 1-12in.....

    I've never had any real problems being loud through my 1-15in cab......

    I come to terms with the fact that 90% of my tone is in my Sansamp pedal and Jazz bass.......my amp is almost a back up.....

    I'm thinking I'll upgrade my GK-400-III to something newer and/or more powerfull.....

    I'm also getting rid of an old Eden WT-300----nice tone, but I don't like the compressor....

    If your tone is in your Sans I would look at getting a power amp and running the sans through that

  12. Some of the 400RB-III's had a fan issue. Make sure your fan is coming on when it gets warm. If not. Contact GK and have it fixed.

    More power, I say!!!

    GK is very affordable... so why not?

    thanks all!

    I'm gonna see if the fan is coming on properly.....

    I like having the flexibility of having a full bass amp (not just a power amp) and the sansamp pedal....lots of flexibility

    otherwise, I've always had good luck with GK stuff......not really the most sexy cool gear, but rock-solid well designed and generally trouble free.....I might just use this as an excuse for a bit more power and a new amp!
