Looking for a used GK amp

Discussion in 'Amps and Cabs [BG]' started by johnson79, Jan 5, 2014.

  1. So I'm in the market for a used head and cab and would appreciate some guidance.

    Thinking about a used 400, 800, or 700rb. I'd love the 800 or 700, but the price difference between that and a 400 is pretty broad. So my question is if the 400 would be powerful enough for a punk/hardcore band. I play a passive pj bass.

    Probably going to be playing small bars and clubs. Thinking about a 4 ohm 410 cab. Maybe a 410hlf. What are your thoughts and experience on this setup?
    Is there another head I might want to think about? $200 is what I'd like to spend on it.

    Hey there... I've played GK 400RB's through Ampeg 410's for years... I don't know how loud you really need to be, but I have never had a problem being heard over some pretty aggressive bands. In fact, I don't even drag the 410 around anymore - the 400RB is plenty loud through a modern 112 w/ horn for all but outdoor gigs. Oh... and that tone... !

    Used to have the 800RB... didn't need it, and I actually prefer the 400RB tone, maybe because you can crank it a bit more. Also, all my cabs are 4 ohms - recommend them over 8 ohm for the 400.

    Good 400RB's can be had for around $300. Go git 'em!
  3. Thanks for the reply. I'm definitely looking for a 4 ohm cab. I don't think I'll need more than that. I'm going to be doing bar shows, so I think the 400rb and a 4x10 will do fine for me. I've seen them from $150 and up, so I'm just going to be on the lookout.

    I've had my GK 400RB since 1991,I used it with a Carvin 410 for many years then I replaced the Carvin with a 4ohm. Avatar B410..Great Rig and I have never had to turn it up past 1 oclock,its plenty loud when I need it I play passive Fender and Squier basses,the only active bass I have is a Ibanez ATK 300,this amp does it all...:)

    I used a 800rb for a year and it was way louder then I ever needed to be. A 400RB would have been fine

    The 800 is great for bi amping which i never do...
  8. Yep, a G-K 400RB into a nice 4ohm 410 cab will totally rock.

    I've also used (and still use) the 400RBIII with 4 Ohm load (first an EBS Proline 410 and now a pair of Aguilar 112) and the amount of sound is enough to piss off at least 4 punk guitar players :)

    A feature that I believe is not so good in the MBs is that the RB can take really hot input signals without clipping so the amplifier can produce very high output currents.
  10. Thanks guys, you rule. I feel pretty good looking for a nice used 400rb.

    4ohm.is also the way to go to get the max power out of that 400RB..Look at Avatar cabinets,they are nice and not too expensive they even make the lighter neo cabs now too...
  12. Two GK NEO410 at 8-ohms per cab, will give you a really big noise.

    All 8 drivers (32-ohm) are wired in parallel for maximum voltage applied to each driver.
    400RB-IV calculates to only 33.5 volts at 4 ohms, so max voltage to each driver is important.
  13. I'll definitely look into avatar or GK Neo. I was thinking about the 410hlf, but they don't seem to get much love. I'd really like 1 cab, so I'm looking for 4 ohm.

    ++++all of the above. The more speakers you can run on it with a 4ohm total load the better. I think you can find one for very close to your budget. The good news is, they don't break very often so there's a good chance you will find one that works fine for your needs.
  16. I think a 400RB with a GK NEO 2x12 or NEO 4x10 will fulfill your needs!

    OP.....Ich habe eine 400RB und eine 800RB.

    If you have lots of speakers or big cabinets, like 215's, 412's, or 810's, the 400RB will do you fine with any of them.

    If you are using a single 4ohm 410, I still think the 400 should do it, but then we're getting into "what is loud enough" and do you like your loud to be able to be "cleanish" when you want to or growling all the time?

    700RB gives you both whenever you want, it's a great amp, but it's not quite the same as the old 400's and 800's....those are hard to beat.

    FWIW, I used to use an 800, now I use a 400, just so I can crank it to kingdom come and still get asked back. ;)

    A GK amp and a sealed Ampeg cab full of 10's is a thing of beauty. The 410hlf.....not so much, IMO. The GK amp helps "undo" a little of their mud, but not enough, IMO.
  19. Anyone have an opinion on an Avatar 2x12 4 ohm? Or would a 4x10 be a better fit? I like a ballsy sound. Not clean, but not overdriven. Am I on the right path?

    I have tried many many cabs and the best sounding one with the GK was the EBS 410 Evolution Proline 2000. Amazingly loud, great bottom end, but still defined, clear and growly. It cuts through the mix wonderfully and does not interfere with other instruments so in a band it is just perfect. Why I changed it? Because it weighted almost 90 lbs. New ones are a bit lighter but not much (78 lbs).
    For a gigging bassist, I prefer to use 2 1x12 cabinets. Moving them is much easier than a 212, and that configuration gives me a lot of flexibility. I can take 1 cab to small gigs, and with two it is enough to play anywhere.
