TC Electronics Rebel Head. Spec gave me a laugh.

You've said this in every thread on this product, Jimmy. What exactly did they tell you to make you think this? They had 1700 people apply for a program where they chose about 30 players from varying regions, styles and experience levels. At no point did it appear to be a favorites contest. What could have been an acceptable outcome? Loan out 1700 sets? You were interested enough to apply, but by luck of the draw you didn't get to participate so you've made it your mission to badmouth tc at every opportunity? I just don't understand. :confused:

I'm not picking a fight here, either. You're opinion is one of my favorites on TB. You generally shoot straight, and while sometimes come across as a little curmudgeonly, you also rarely seem snide. You're a good dude. This is a good product. You hating this product seems strange to me. :help:

The only thing I thought was funny is the impedance. As reported in BP magazine, the amp's minimum impedance is 4 ohms. The two cabinets are both rated at 4 ohms. So, despite the pictures showing the head on top of a stack of both cabinets, you can't run it that way.

Not true. All three cabs (210, 212, 410) are 8 ohms. Two of them would equal 4 ohms. They do state that you can run up to three of their cabs, but they don't recommend doing that with other cabs. How can this be? Impedance is not static. Every driver (and group of drivers) have an impedance curve. If you know these curves you may be able to make a combination that does not pose a risk to the amplifier, even though the published nominal impedance would fall below their recommended spec for the amp. You may find a combination of cabs that will run fine with a computed nominal impedance below 4 ohms, but they can't guarantee that. Electrical physics can be a tricky fellow sometimes. :)

Ok... I'll try again.
TC in conjunction with Tannoy developed the cabinets in this line. They indicated that as a result of their working with Tannoy in the design, they are fully aware of the impedence issues that their cabinets have.
I'm not an expert on this stuff by any means, there are many here who could tell you better. All I know is that they say you can run any three of their cabinets (now three available) without concern regarding impedance, with this head.
They don't not however suggest using other manufacturer's or combination that drops the load below 4ohms.
I guess if your engineers who designed the head work hand in had with the engineers who designed the cabinets, they SHOULD know what their cabinets and heads are comfortable doing.

Or you could just read ettsn's post above for a better explanation!

+1 Nice post.

Impedance is dynamic. The rated impedance of a speaker system is technically the "nominal" impedance, but the actual impedance varies with frequency as well as other factors in cabinet design. I know that in the mid to late 80's Peavey had a sub woofer (no one called them that then, they were "bass bins") that had a 4Ω driver but the cabinet was rated at 8Ω (or the other way 'round, I don't know for sure). The people at Peavey explained that it had to do with how the cabinet loaded the pressure on the speaker, if I recall correctly. Of course that was 24+ years ago...

ettsn- Thanks for the correction. I don't know if BP wrote it incorrectly or if I mis-read it but I was sure they listed the cabs (in the issue with Phil Lesh on the cover) as 4Ω each. Perhaps another example of what happens when the good editor is laid off.

In Denmark we have a very dry sarcastic humor. And we are not afraid to make fun of ourselves. I've talked to some of the guys behind the Rebelhead - most of them just fellow bassplayers like you and me.
It's just danish humor! Don't take it so seriuosly!
Actually the danish word for mood is "humør" or humor so we have fun in our DNA. Or something like that.... he he
Best regards from Denmark,
Jesper

I wasn't the least bit offended. Hell, when coworkers learn that I play bass and ask if I will bring one in and play it for them, my immediate response is "bass is boring all by itself!" Sure, I know that some of you can play entertaining solos, but the fact is that many folks don't care for bass solos no matter how well they're played... hence that "when the drums stop, the bass solo begins!" joke. :p

Hey Ken! Haven't seen you around the site much lately. Hope you are well! And... +1

And that reminds me of the old joke of the marriage counselor/therapist who always has a loop of famous bass solo's by Stanley, Ray Brown, Victor Wooten, etc., etc. constantly running in the background during his therapy sessions. A couple finally commented on this, and asked why all the unusual 'bass music'. He responded 'it's the best way I've found to get my clients to open up, since everyone talks during the bass solo'.

I picked up an RH450 last week and love it. And it really is simple to use.
Playing through Tecamp and Tech Soundsystem cabs, it does everything I need from amp.
The humour is a little northern european as already mentioned so no one should take it seriously at all.

You know, it's like telling your friends their baby is ugly. We all know it's true, but what purpose dows it serve?

BTW, anyone know any famous Danish comedians? Didn't think so ;)

Thanks, Jimmy. But I have to confess...I have no idea who this baby is. I found this pic on the internet. :rollno: Just kidding. This is my first granddaughter. But to get back on topic, several times I've heard her laugh at Danish jokes. And I just know she wants me to buy the new TC Rebel head. :D

" Simplicity is always important to bass players and the Rebelhead is no exception. The front panel features the usual suspects, input gain, 4 tone controls and master level - every bass player can now use this!"

Huh, I never had a problem with this. Just turn all the knobs up full, like in the DEER SAUSAGE video and hammer away.

"Rehearsal Input - Bass is a pretty boring instrument on its own. Every player recognises the need for background music when practicing"

Yeah explains a lot. I put on prerecorded Bass music for sex and she gets a headache. Took a bass amp ad to make me see the error in my ways.

Ah sorry to join the party so late, but I just got here!

Anyhow, you think the specs are bad this video demo from Namm is almost as bad, there is this undertone of 'we simplified the design to fit the player'.... or maybe I'm just reading too much into it?

IMHO - I think they did over-simplify this head. It doesn't automate as well as it should. All the electronics are in it, it's just too closed box.

Now that they've come out with the RH "Classic" for people who don't want automation, they can get on with upping the features of this this head.
