Need info on Gallien-Krueger 1001RB series1 Please

[DJ Bebop]

I am considering a used, old school Gallien-Krueger 1001RB series1 bass amp head. Please hip me to it, good to own, bad, what?

I had one for a long time- I have nothing bad to say about it, always loud enough, growled when I wanted it to, etc.

I did send it back to GK at one point for a upgrade which brought it more in line with the series 2 specs and changed the light from green to blue. To me, it didn't seem to change the tonal character, but it seemed like a good thing to do.

I'd buy one again, if the opportunity presented. Heck, I'd buy my old one back from the guy I sold it to...

What is the wattage in 8ohm, 4ohm. I dl'd the manual, it says 540watts for BOTH 4 and 8ohms. I don't think thats right?

It's not right. It will deliver 540 watts at a 4 Ohm load, it will deliver less into an 8 Ohm load. In the owner manual it says about the 1001 RB combos, in part "The 1001RB combo electronics are identical to the 1001RB head and are rated for the same maximum power output and speaker load (540W into 4 Ohms, and 50W into 4 Ohms). Maximum power is achieved by connecting one 8 Ohm extension cabinet (such as the 210RBH, 410RBH, or 115RBH) in addition to the combo’s internal 8 Ohm speaker load. To drive more than one extension cabinet, the combo’s internal speaker can be disconnected by unplugging the Speakon cable connected to the combo’s back panel. Below is a detailed description of the maximum loads the combos can drive." Even though it doesn't explicitly say it, you are getting less watts delivered to an 8 Ohm load by nature of the SS design. I hope that helps. Cheers.

I think it was in the neighborhood of 380w into 8ohms.

This head has been my workhorse for over 2 years now. It's takes a beating, and never skips a beat. I have it paired with an 8ohm SWR Goliath, it sounds amazing, and has more than enough power for any gig I've ever played, even outdoor festivals.

I debated on getting it upgraded to series II internals, but figured if it's not broke, don't fix it.

Thats good to know. I am going to use it with a GS 112. What do you all think?

It's more power than you'll need. But if you're careful with the volume, it should make for a good tonal match...

I've had mine for about 2 years and still kicking.

[DJ Bebop]

How does it compare with the 800RB? There's one of those available too.

Whats the dif between series I and II

The 800 is also a good head, dead quiet because it has heat sinks and no fan, it weighs more than the 700RBI and you can make the 700 sound like an 800 and have many other tonal options. The 800 is a lot better at bi-amping because you can chose how many watts go to each cab, whereas the 700RbI has 2 internal amps, one is the main amp that delivers power to your drivers the other is a 50 Watts @ 4 Ohm tweeter amp that needs to be attached to G-K cabs in order to bi-amp in this way.

There is no difference between the 700RBI and II except the amount of power available from the main amplifier ... In the 700RBI it delivers 540 Watts @ 4 Ohms, in the 700RBII it provides 700 Watts @ 4 Ohms. And as has been mentioned, you can upgrade the internals to the 700RBII specs by sending it in to G-K if desired. Hope this helps. Cheers.

I was looking for compairing the 1001RB series I with the 800RB. I don't know if you knew that or if that's what you meant. But thanks anyway!

First off the Bi-amp in the 800 sends 300W to the main amp and 100W to the high side, you just have the ability to send another 100W to a 3rd cab @8ohms (high side). With the 700RB head (380W @ 4ohms I believe) you have a 50W tweeter amp that pushes just the tweets for a crystal clear snap to your sound, something no other amp maker provides along with their cabs! Now the 700RBII head puts out 480W@4 ohms while the 1001RBII head puts out 700w@4 ohms. The 540w figure for the 700RB above is incorrect, that is the wattage for the 1001RB head @4 ohms.

... and thats the one I am talking about the 1001RB I. How does the 1001RB I compare to the 800RB I?

The 1001RB has 540W@ 4 ohms, more than the 800RB head and has the ability to get close to the sound of the 800RB with the push of the 5 string button. The 800RB head is "warmer" than the 1001RB head and the 300W @8 ohms is sufficient with the 540W of the 1001RB being LOUD! The 800RB head does send 100W to a separate cab in full range but there is a roll off to be considered meaning you will get no lows out of that 100W, also I don't think the volumes can be separated between the 300W side and the 100W side. The 1001RB has two separate amps and the tweets are totally separate from the main amp. This is excellent for the thump and pop stuff (slap)! This does away with woofers trying to recreate crystal clean highs and low frequencies at the same time allowing each speaker and tweeter to work independently without bleeding into each other (GK cabs only).

I have been using a GK 1001RB for 8 years and have never had a problem.

I own a 1001RB 2x10 combo and a 1001RBII head and love them both! Using my 1001RBII outdoors with 2x410 cabs I don't think I have ever been turned up past 11-12 o'clock, good "clean" power!

I have owned both and they are both great heads. The only operational difference is the upgrade in power.
Series1 is 300w 8ohm and 540w 4ohm
Series II is 500w 8ohm and 700w 4ohm
Both give 50w to the tweeter for biamping (with a GK speaker and cable).
Basically now the old Series 1 1001RB is essentially a Series II 700RB with blue lights
Can't go wrong with either IMHO
