NAD! GK 1001RB Mark 2!

I have a 700RB-II and absolutely adore it, but have been thinking of trading up for a 1001RB-II. I've not been certain... I was waiting until after completing my rig with a second cab, but I feel like now that I've gotten that second cab, the 700 might be enough headroom. I've certainly been sitting and watching the 1001RB-II listings on Reverb enough...

...and that definitely looks like a guitar 412 to me; not a bass cab.
The 1001RB could destroy those speakers quickly - the Ampeg 410 cab will be much more suited for the 1001RB.

You know - I'm not an expert on cabs, but I do have quite a few guitar ones. All of my guitar ones have inputs that state for 4 ohms or 16 ohms, this Tube Works cabinet doesn't have that - so that would make me 'believe' its a bass cabinet, but heck if I know. Guitar Center sold it as a bass cabinet.

Unfortunately, Guitar Center product knowledge varies wildly - and this seems like a case where they got it wrong.

I looked for online info about TubeWorks cabinets and couldn't find anything authoritative.
@agedhorse might have been involved with Genz Benz when they were making TubeWorks cabs - he can probably tell us if they ever made a 412 for bass.
 
Guitar Center also thinks that these are bass heads:

Other times the description might be for a bass amp, but the picture is completely wrong:

The point being, Guitar Center used gear is always an exercise in caveat emptor.
 
Great Amp! Had the older model, traded up to the 2001RB, then 2008 happened and had to let it all go to stay alive. I'm looking for another one to be main/backup for my GK MB800 which is also great. My only word of caution is that GK can sound a little anemic in a practice context, the gain and volume are too low for the amp to open up. Come gig time though, nothing beats it (subjective of course).

I don't recall any TubeWorks 412's ever marketed for bass.

Don't do it. The 700 hits the rails just right.

I actually preferred my 400RB over an 800RB, having access to both on a tour. And for exactly that reason: I could drive it at a solid but reasonable stage volume.

I suspect that level was somewhat higher when that tour was going, 1992!
 
Keep your 700 and if you want the 1001rbii grab it. The 700rbii gets the rails tone much easier IMO, but nothing replaces the emense heft and headroom of the 1001rbii and that's why I keep both. YMMV but I'd miss my 700rbii's way too much if I went 1001rbii only.
I've been wondering if I'd ever want to get a 1001 to supplement my beloved 700. The rails tone is *it* for me and I have never felt a need to be louder than I am with two bag end 15"'s

I have both the 700 and 1001 RBII and love them. They give me a nice punchy sound even when we are trying to keep the stage volume down. I prefer the 700, I think it's a little warmer sounding but that could be my imagination.

They are pretty bulletproof. I just had them both serviced, they were getting a 60 cycle hum that was getting worse. The one just needed the pots cleaned, the other I had dropped and damaged the output jacks. It still worked and the tech said I was lucky that it didn't short and kill the amp. I also had a pipe freeze and burst while I was away for a few days. It happened right above my music room so a lot of stuff got drenched. I don't remember which one, I think it was the 1001 but it sat under pouring water for a day or two. Tech cleaned it up and dried it out and it has been fine. That was probably 10 years ago?

I find the tone stack to be very responsive and a little adjustment goes a long way. I start everything at noon when I get to a new venue. I usually roll the treble off a little to get rid of the clank and string noise. That might go to 10:00 at the lowest. I go up or down on the others, usually not more than 1/2, like 11:30 to 12:30 depending on the venue. I did have one place with a concrete floor and really high ceilings that was so boomy I had to roll the low mids and bass both down to 10:00.

Great amp! Have fun with it. I suggest modular on speaker cabs. I started with a 4x10 and added a 2x10 but wish I had two 2x10's or something similar. As long as we have good sound support and I'm going through the mains and subs, I usually only use one 2x10.
 
I was wondering about this -

However, Genz Benz was a speaker builder at that point in time, not a bass amp specialist...and that definitely looks like a guitar 412 to me; not a bass cab.
The 1001RB could destroy those speakers quickly

Because of this -
Guitar Center sold it as a bass cabinet.

But this -
I don't recall any TubeWorks 412's ever marketed for bass.
Makes me kinda glad I didn't act on that curiosity.
