    Hello everyone,

    I'm going to get a new head; I think I'll go for a GK-RB.
    I tried a GK400 RB IV and I was impressed by its power :eek: . With a markbass 4x10 cabinet (8ohm, 400RB was supplying 180W) it was really loud. Go figure how loud it is, working at 4ohm with its 280W :)
    Now, I think that's enough if used as on-stage bass monitor
    then sending its D.I. to PA system. But, would it be enough power playing in a rock context, in small/medium clubs without PA? Should I go for 700RB II?

    Thanks

    I've owned th 400. it is amazing. but if in doubt go for the 700. It's nice to have the headroom.

    The 700rb-II is a different beast and IMO a better one.

    EDIT: see second post.

    Get the one with the most headroom you can afford. Period.

    I started off with a 400RBIII, then I went up to a 1001RB. This week I went up again to a 1001RBII (woo hoo!):) I will keep the 1001RB for a backup;) Like said above, get what your bucks call for!

    I have a 400RB-III, looking to upgrade soon to the 700RB-II or 1001RB-II sometime soon. IMO the tone is just about identical on both (Sorry to step on toes Figjam) but they use the same preamp design. The only difference in the 400, 700 and 1001RB is the power ratings pretty much.

    I just picked up a used (like new) 400rb-IV as a small easy to move back up for when i play with other people at they,re place and have to bring a head . It's a cool little amp i was surprised by its power. Like I said its a back up for jamming and stuff like that , I leave it in the car for gigs just incase some thing would happen to my main rig I have a way to finish the night. Now If this is going to be your main amp I would go with the 700 or 1001 having to much power availible is way better then not having enough If you look around you can pick up a used 700 pretty cheap

    Thanks for answering! :)

    Those of you who are using a 400RB IV, have you ever had problems in getting enough volume (I mean, playing live)?

    O.k., Now STOP!

    1. Those are both great heads.

    2. Get the most power you can afford.

    3. Don't try to just 'get by'. Make sure that you have enough power.

    If you can afford it, get the 700RBII

    :D

    +1 Listen to this guy! I started with the 400RBIII (great head) then went with the 1001RB, I'm currently using the 1001RBII as my main head with the 1001RB for a back up! You may run into situations where you may need more power in turn up the 400 head, it will get slightly louder but will not sound more powerful. The power is what's going to move your cabs not loudness! When I used two cabs I suffered from a lack of power when I turned up the volume thus the jump to the 1001RB, When I did outdoor gigs with my 1001RB 2x10 combo and my 1x15 RBH cab I got through the gigs but I could have used more power. Power use something that is also usable at low volumes as well as high volumes, it allows you to have a fuller sound at lower volumes without turning up the volume knob. That's what the extra "headroom" will do for you!

    ^ i agree. twice.
     
  15. over at www.rmcaudio.com they just quoted me 500 for the 700RB-II and 600 for the 1001RB-II so I suggest if you want one get it from there. My local shops want $600 for the 700RB-II.

    I took a printed out price quote to Sam Ash from Riks for 600 bucks and they matched it! I offered to pay the tax! $647 for a 1001RBII out the door!:)

    I agree with all the others about getting the 700RB-II if you can afford it. I have one as my main head, and it sounds simply huge. With an efficient 4x10, I think you'd be fine in medium clubs without PA support unless you have guitarists playing at insane levels through big rigs. In most places I play, I can get by with this head and just my Neo112 cabinet (with PA support). At my last gig (the first with my new band), my bandmates started laughing at how loud it was when I powered up.

    Here, local shops want 690€ for a new 700RB II, 545€ for a 400RB IV. This one is available at the shop while the 700RBII would take at least a month to arrive, by ordering it now...that's the matter..
