GR Bass review

Actually I was complimenting your cliënt service .
And I'm superhappy with the amp and speaker! They sound amazing!

I get that, but we’re sorry when this happens. For us it is very important to help our customers, their happiness is the best advertising.
Thanks again
 
GR Bass Staff,
any good news on when AT cabs and amp production will resume?
With a ONE 800 and an AT212, I think that I have more inventory than any of your US dealers.

Like almost all amplifier manufacturers, we had delays in delivering components.
In the coming weeks, however, the new material will arrive at our American distributor.
 
Question for @GR Bass Staff or for the public here! I have a One800 head with two AT Cube 112 cabinets, although I often use only one cabinet at low volumes. I have no complaints, it sounds excellent!

My question is, does the One800 amp normally run very hot? Unless I turn it to Studio mode, the fan almost always turns on after a short time in operation. It feels quite hot to the touch after being in Studio mode for a while. One thing I noticed is the fan takes cool air into the side and blows warm air out the bottom, which I think is backwards from the ideal way to dissipate heat and backwards from how other amps do it. Is this correct and is it normal?

I did get the One800 new a year ago, so it has a 5-year warranty... I'm not worried about failure right now, but in less than four years I will be worried. ;)

Hello,
It is normal for the fan to work like this.
It is activated when it reaches a certain temperature.
It should not be too hot, but it is normal, given the small size, that it warms up slightly.
Anyway don’t worry, from what you write it seems to be working fine.
If you need anything else please email me at [email protected]

Hi, We are the Canadian GR Bass partner/dealer. We know John at Sonata Marketing, and GR Bass in Italy very well. Sonata is unable to respond because of being affected by the widespread power outage in Texas.

I'd like to try help with some issues raised in this thread. GR AT cabinets don't require any sound dampening materials. The carbon fiber walls are uniquely designed in conjunction with the cabinet drivers. The carbon fiber wall density is customized for the cabinet.
Regarding the resonance or weird sounds at high volume levels; it shouldn't happen. It's possible that specific cabinet has a defect. It's hard to diagnose it without being there and hearing it.
Dampening? How does it get wet?
I believe the acoustic term is damping.
That’s what I was taught in physics class.
 
For those who've used the regular, wooden 2x12, what are your opinions of the cab? Does it work well ar low and high volumes? Is it boomy at all? It's there good separation between staccato notes? Would it work well with a 150 Watt tube amp?

This and the GK Neo IV 212 look like interesting mid-size cabs for use with a tube- or moderate-power solid-state hear and are about the same price.

Thanks in advance.
 
Just got back from rehearsal and I was VERY pleased with the 212 Slim. As shown in the previous photo I had everything loaded onto the cart but when I got to the studio I just carried everything in, it was all so light and less trouble than messing around with the cart.

Tonight I used the Quilter BB800 amp and finally got to see the speaker cones really move. At such volumes I did experience head creep and every time I moved it back to the middle it would always move back to the same place and stay there but not fall off. Still, I will get a piece of shelf liner or use a towel to prevent movement. Stability of the rig was fine with the smaller and lighter BB800 head.

My guitar player kept commenting how diamond clear the sound was but with lots of beefy bottom end too, which I concur. Much nicer sounding than the crusty olde Peavey and rattling 4x12 cabinet that I usually have to play through over there, and definitely more light and compact.

I am really enjoying the sheer simplicity and power of the Quilter BB800 with the sonic clarity of the GR Bass, both at home and at rehearsal. Next week I will try a different rig and see how it goes, but it will be very hard to beat the ease of transport, great sound and immense power of tonight's setup.
