Genzler - new amp for Jan 2016

[Doug Parent]

oh nuts.

 

[rodl2005]

Looks great. Congrats Jeff. If it's anywhere NEAR as good as your previous offerings, I'm sure it'll be a KILLER amp.

 

[Dave W]

Cool!

It does look very similar to the Streamliner. Priced very nicely too. I'll be picking one up I'm sure. I'm in the market for a backup amp anyways

 

[jnewmark]

Looking sweet.

Wonder why the 2.67 ohm min vs 2.0 ohm. Not sure what design elements would be necessary to go all the way to 2.0, but it seems like the one thing that pick out as odd.

Yeah, why not 2.0 ohm, or maybe it's got something to do with their cab line ? Seems kinda odd.

 

[murphy]

could be to avoid using current limiting to get it to do 2 ohms

Well, if you wanted to use two 4 ohm cabs, you're screwed.

Well, if you wanted to use two 4 ohm cabs, you're screwed.

Or, I suppose, at that price point you just buy two of them?

Thanks for the interest.
When designing amplifiers there are always trade-offs that need to be addressed within a specific set of technical parameters. The manufacturer's lowest recommended impedance is 2.67 Ohms. While the module may be capable of 2 ohms it does come with more risk.
After much discussion between engineering teams and balancing the "variables" within the modules design, manufacturing tolerances and cabinet impedances in the market place, we chose the recommended 2.67 ohm impedance rating. This also fits very well with our cabinet offerings.
And our position is in no way a comment on how others choose to design this module into their products.
I hope this info is useful on this subject.
Thanks again
Jeff

A much appreciated response. I've read/heard that there are really only two power sections in common use today, so I wouldn't be shocked to learn there are other offerings from competitors using the same power section and opting to market them as 2ohm.

 

[RoadRanger]

Being able to run three 8 ohm cabs is awesome ! I used to do that in the bad old days with 4 ohm amps .

It isn't bad per se. If people never pushed components over their recommended limits, we wouldn't have a single overdrive pedal on the market.
It's all about using components to the best of your needs and finding ways to deal with the limits.

 

[CaptainWally]

No tube in there then?

mmmmmmmmmmmmm?

Congrats on the birth of your latest child Jeff!

which they probably do just fine though being integrated into the whole amplifier design the same power module may react differently from design to design due to different preamp components or reduced ventilation due to size or other. Another possibility is that jeff intends to continue with the excellent customer support from GB that I read so much about here at TB and rating these at 2.67 rather than 2 ohms will help reduce warranty claims

So what does this mean in real terms .. Does this mean that I could actually run two 4 ohm cabs as long as I didn't push them too hard or would that still not be recommended?

 

[samson3382]

No.

I wish more folks realized this.

It means it wouldn't be recommended. It might work but isn't suggested. You can run a 4 and 8 combo and still be playing by the rules

 

[Jeff Genzler]

Yes all of this is correct. In our research and past experiences we found just as many (if not more) requests about running an 8 and 4 ohm load together than two 4 ohm loads.

I have to say this makes me consider retiring my beloved neo-pak. I love how you get full power into 4 ohms but still can add another 8 ohm cab if you want. Years past with a previous amp I had make a choice when I bought the cabinet. Either go 8 ohm and be able to add to it or go 4 and get full power from the amp. I chose 4 and later wished I could add to it.


Nice work on this one Jeff
