It's time for triaxis...clean tones question...

[virtu]

Well it's time to expand the boogie family...and to buy the TA...

So far i've had the chance to try it in a studio jams but only for the distorted tones (superb!!!)
For the clean tones i'm looking a funky crystal clear and a fat jazzy tone...

Can the TA gives me that kind of cleans?

Need your opinion my friends!

Thanks!

I think the quality of the clean tones depends more on the power amp you are using. If you are using a high quality and well-matched power amp, you will be able to get nice cleans with the Triaxis. The 2:90 sounds very nice for cleans due to its simulclass configuration. Very jazzy, crystal clear or slight break up - I can get anything with the Tri/2:90.

What power amp will you be using?

I'm thinking for the 20/20. Only because i'm in the process to downsize things. I use to have the 2:50 and it was a great amp. But the 20/20 is my choise only for the weight and portability...what do you think?

(btw...and just a tc g-major in the loop...)

funky crystal clear = Rhythm Yellow

fat jazzy tone = Rhythm Green

As ando states, the power amp is a huge factor in the cleans, but the tones are there.

I use a 20/20 with my TA. I can have great cleans, round, fat, crispy...
But I suggest you to try a 12AT7 in V2 (input tube for RHY and LD2 channels). It really opens your sound, and you won't loose too much gain for LD2. LD1 red is even more usable with that configuration (V2 is drive tube for LD1).

Thanks guys...
And yes, i've been told that if i try lower gain tubes in V2 the results are stunning!
I have another question though...
Is it true that the 3rd version of the triaxis has the lonestar cleans or not?

Changing V2 will change your clean and LD2 sounds, but it won't affect LD1. It's not correct to say that V2 is the drive tube for LD1. It is only for rhythm and LD2. If you wanted the same effect on all modes, you would have to do the same thing to V1 and V2.

Sadly, this is only an untrue rumor

A triaxis with the LS cleans would be the ultimate preamp ever....i have the roadster and it's cleans (LS) are amazing.........anyway....

According to schematic and tubefreaks' page, yes it is !

V4 is only engaged when in LD2 mode. And my tests says that too !

Hmm, well now I'm really perplexed! When I bought my Triaxis, it had a problem which turned out to be related to the concentric output pots on the front panel, but I wrote to Mesa and was told that V1 is the input driver for LD1, V2 is for all other modes, namely Rhythm and LD2. As you say, V4 is a post gain stage for LD2. V3 is a Lead/Rhythm mixer.

This seemed to agree with my Triaxis manual. Now, if you are saying that V2 is also active during LD1 mode that could mean one of two things:

a) there is something wrong with your unit (unlikely I guess, since you say that the schematic supports this, I haven't seen it)
b) The simple explanation is not a complete one and V2 is involved in a different way with LD1.

One thing is certain, V1 is the input driver for LD1. So I don't follow you on that one. Nobody is disputing that V4 is only active when LD2 is activated, and the mere fact that you felt you had to point that out makes me wonder whether we are mis-communicating about something.

To be clear, this is what the manual and the Mesa guy say:

V1- Input driver LD1
V2- Input driver for all other modes (Rhythm, LD2)
V3- Rhythm/Lead mixer
V4- Post input LD2 gain
V5- Effects return

Going in that basis, I'm surprised that you say V2 is the drive tube for LD1. There is no mention of V2 being involved in LD1. Could you expand on this for me? I'm not going to say you are wrong because I haven't got the schematic and I haven't looked at this in any detail. Just need more of your information for it to make sense to me.

Take a lot to that schem :
http://tubefreak.com/triaxis1.jpg

In LD1 mode V1A is the input tube. The signal then go to the TX4 board, and the only return path go through V2A. Or this schem and I may be wrong :? .
Also In LD1 red mode, how could we have a so saturated signal without additionnals triods ? If V4 is involved only in LD2 modes, V2 must be the one !
A simple test is to remove V2 and play through LD1 mode.

If anyone knows something about that, please give us a correct answer ! :wink:

Based on the full Triaxis Technical Manual, the schematic shows that:

R1 Green and Yellow:
V2A->ToneStack1->V2B->V3A->EffectsLoop->V5 (Left is V5A, Right is V5B)

LD1 Green and Yellow:
V1A->V2A->ToneStack1->V2B->V3A->EffectsLoop->V5 (as above)

LD1 Red:
V1A->V2A->V2B->V3A->V3B->ToneStack2->EffectsLoop->V5 (as above)

LD2 Green and Yellow and Red:
V2A->ToneStack1->V2B->V4A->V4B->V3A->EffectsLoop->V5 (as above)

So, I would characterize the tubes this way:

V1: V1A used for LD1 modes. V1B never used.
V2: Used in all modes
V3: V3A used in all modes, V3B used only in LD1 Red
V4: Used only for LD2 modes (overdrive circuit)
V5: Used for all modes as clean gain after effects loop
