I believe the successor to the Triaxis may be called the "Transaxis" (if going by Mesa Boogie trademarking this name is any indication, as discussed in previous posts...)
I have a feeling that they may be working on it right now. Maybe I'm getting ahead of myself here, but I'd love if it was announced at NAMM next year.
I'll chip in and put across some ideas for the new preamp (if it's not too late that is!!!!) Some of these are already mentioned by others:
* Knobs - similar to the motorised knobs to that of the Soldano X99 Preamp.
* Motorised EQ knobs.
* No compromise in tone or features ( I was disappointed with the omission of certain switches/knobs (e.g: Pull Deep) on the Mark V. Don't get me wrong, technically this amp was quite an achievement. I thought the Cleans and the Crunch channels/modes were awesome. But I couldn't replicate my settings and tones of my Mark 2C+'s on the Lead channel, like I could with the Triaxis. To my ears, the Mark 2C+ mode of the Triaxis sounds closer to the 2C+ than the Mark V does. I felt restricted on the lead channel of the Mark V.
* An expansion on the available modes. Going by the name of Transaxis (assuming this is the name), I think we could expect they will implement the recent developments achieved with the Transatlantic series of amps. New Modes for VOX and Marshall (Plexi) in addition to the current Fender and Boogie Modes would be awesome! But I hope it doesn't emit certain features such as the lack of A Presence knob as with the Royal Atlantic).
I want this thing to give the Axe FX a run for it's money, as far as the number of amp models are concerned. I know, I know, the Axe FX can't beat tubes for realism and quality, but if the Transaxis were able to have many more Modes available, it'd be killer!
* A tougher interface. I'm sure many of us have come across many used Triaxis' that had flaws with the face of the unit (buttons, digital no's). I think having motorised knobs or another similar idea should overcome this.
* I wouldn't mind if it "HAD" to be 2 backspaces high, as this would be a small price to pay for more features.
Additional Power Amp features (to the successor of the Simul 2:90):
These may be unrealistic or overkill, but here goes:
* Now, how can they achieve a power amp that can cater for 8 x 6L6 + 8 x EL34 and other possible tubes, without switching them out is maybe wishful thinking! But they did achieve this to some extent with the Road King. I thought the voicing of the Crunch channels via the 6L6's on the Mark V was quite an achievement. So maybe they don't need to cater for sixteen
power tube sockets on the successor of the Simul 290 power amp, if they voice the British modes on the Transaxis & the power amp right for 6L6's.
* At least having the option of using 6L6's or EL34's in the same sockets would be cool.
* The power amp may need to close in on the attack that is felt to that of a head (if it hasn't been achieved already with the Simul 2:90). I haven't played through a 2:90, so I don't know... maybe others can chime in here, correct me if I'm wrong!.....When running my Triaxis through the Return input of the FX loop of my 2C+, I felt it wasn't as tight as the 2C+ going by itself with the identical settings (minus the 2C+'s EQ) through the same speakers. Otherwise it did "sound" identical to me. It just felt slower and not as urgent in the attack compared to the 2C+ by itself when doing a certain type of percussive chugging on the low strings. I hope this makes sense!
* If Mesa Boogie feels the need to use a smaller coupling capacitor for the Mark 2C+ mode (as they did with the 2C+ mode of the Mark V), then please allow for the larger value coupling capacitor to also be available to be switched in....to whatever mode is being used.
* And finally, built-in attenuator/s in the power amp would obviously be beneficial.
What do you guys think?
