Triaxis, or Mark IV Head?

[mightywarlock]

I already own a 2:90, and have sold my Triple Rec head a few weeks ago, and have been trying to decide whether I should pick up a Triaxis when i can find an affordable one...as i am looking for the mark IV sound as well, as more versatility.

so...

can the triaxis get the Mark IV sound completely?

or is there something about the Mark IV that only the Head will get me?

I've been using triaxis since 1994.
I had mark IV.
I sold it because triaxis give me any mark series amp tones.
Plus you can save your presets and it's midi.
What more could I ever need??
Nothing.
I will never change mine for anything.
With Mark IV you will spend hundreds of hours until finding your tone.
Triaxis already has the best tones ready,just a few turns and you will be in heaven. :wink:

So the Triaxis has "factory" presets with suggeted dialings in place + plus you can tweak and set your own?

I own both a Mark IV and a TriAxis-50/50 rack, and without a doubt I prefer the Mark IV hands down over the TriAxis. Running them side by side it just sounds much better to me then the TriAxis.

Triaxis- 50/50 :? Have you ever tried a 2:90 with your Triaxis? If the answer is NO, and you have not experienced HALF/ DEEP / and MODERN Drive modes you have short changed not only your TRIAXIS but your ears my friend. The TRIAXIS / 2:90 in my opinion is the GRAIL TONE :shock:

+ 1.000

People use triaxis with other power amps forgeting that 2.90 is its perfect pair.
So if you use other power amp you'll limitate triaxis tones. :wink:

 

[mightywarlock]

so seeing as i am looking at pretty much the same amount of money, it sounds like i would be better off with a used Triaxis...

now depending on model, or version, should i be looking at a 2.0 no phat mod? seems while the phat mod is sought after, the non phat seems to be preferred.

is this true?

 

[18&Life]

I don't use LD1 so I don't care about it.
Always 2.0 because of midi.
An used one maybe 1.000 USD.

TONE HEAVEN :twisted:

Random question: Why is it neccessary to have eight power tubes in the 2:90? Doesn't that seem a little...much?

 

[18&Life]

Because you can turn it down half it's power.
I think it is .

It's 90 Watts per channel hence the 2:90. 2 channels...A&B each 90 watts.

180 watts is too much but it is stereo so it's like having a Mark IV plus a simul sattelite.

Half drive does not lower the wattage it just makes more distortion in the power amp you still are running all 8 power tubes at full power.

I will tell you guys my opinion in a couple of weeks when I test my Mark IV B against a TA/290 setup. I am dead set on keeping the Mark since i got a great price on it but I am curious myself to see the differences in feel of the two. There's no replacement for knobs.

Greg

Well but if half power doesn't lower the wattage,why it sounds lower? :shock:
I mean I think less watts=less volume ???
An amp with 100 watts is louder than one with 50 watts.
So are you saying that less watts doesn't mean less volume ?
:shock:

 

[visualrocker69]

Lower wattage indicates lower output potential, probably. Doesn't necessarily result in a lower volume.

 

[18&Life]

But if it have lower output,it'll sound lower(less volume,less sound whatever) , not ??????

Are we having some misunderstand with terms ? :lol:

Half power does not lower the wattage. It actually has no effect on the power tubes. Email mesa about it. Or read the schematic:

When you engage half drive:

V2/V3 voltage gets lowered (which is the phase inverter for each quad of power tubes) From 25 volts to 14 on pins 8+3 and from 68 volts to 9 volts on pins 7+2.

On pins 6+1 the voltage goes from 311 volts to 428.

The schematic can be found here:

The result is that the phase inverter preamp tubes (V2 and V3) get distorted faster and their output is lowered. The manual does not state that the wattage is lowered but only that it distorts quicker.

Thank you dude but I don't want the schematic.
I don't know how to read it.
I was trying to understand why lower wattage doesn't mean lower volume or lower sound.

When I use half power,2.90 sounds lower.Isn't it less output or less volume ?
Humm physics :lol:

 

[visualrocker69]

No, volume is percieved. At some point output can continue to increase but percieved volume is indistinguishable (you can't tell the difference).

And between 50 and 100 watts, at a certain point, it'd be the same.

When you get into acoustics and playing in different areas, there are more things to consider. Then it really IS about physics, pushing of air, etc.

 

[18&Life]

Having a 50 watts amp on its max volume.
Having a 100 watts amp on its max volume.

I think 100 watts amp is louder.

1-So having less watts doesn't mean you have less volume ?
2-If not, less watts means what ?

Physics class :lol:

It's about how hard you are driving the speakers and output tubes, not wattage and not volume. You can run a 400 watt 4x12 cab with a 15 watt head and it will sound louder than a 100 watt head pushing a 25 watt 1x12 speaker. In essence half drive isn't pushing the speakers as hard.
