To start with, I should probably state what my setup is and what I wanted out of the amp. The guitars I own are an Ibanez JS10th (DiMarzio FRED and PAF Pro pups) and a EBMM JP7 (DiMarzio CrunchLab7 and LiquiFire7 pups and piezo). They plug directly into the Triaxis (version 2, non-phat), output to a TC Gmajor2, then output to the 2:90 (v1, blue LED). Last but not least, I connect to a single Marshall 1912 cab via a THD Hotplate. I went for the Triaxis because I wanted as broad a sound scope as possible but as compact as possible. My guitar influences would be Joe Satriani and John Petrucci (duh: see guitars - total fanboy...) but I play regularly in ceilidh (pronounced Kay-lee - look it up) bands and in my local church, hence the desire to have as much tonal variety out of as little stage real estate as possible. It was a toss-up between a second-hand Triaxis/2:90 and a Mark V:25 (my brother has one - it's AWESOME), but the availability of the Triaxis on eBay and the lure of just switching on and having every sound I want without dial fiddling was too much to resist.
With that out of the way, here goes with what I've found...
- 1. Read the manual! It's repeated so many times on this board and it really does help.
2. A shout out to Fabiano whose series of Triaxis demo clips on youtube are a big help. I could not get a Lead 1 Red sound until I watched his vid.
3. Another shout to fcampanini for the Triaxis editor. It makes preset edit, backup and restore so much easier.
As with most folks, I soon discovered the limits of the Dynamic Voice circuit: anything above 6.0 and the sound became unpleasant. Therefore...
- 4. Replace the V3 valve with a lower output tube e.g. 12AT7 or 12AU7. The Watford Valves pack came with a Philips Cryo 5751 and I really like it in V3. I don't go up to 10 on the DV setting, but it has become way more usable.
5. Read this: the single greatest thread on this board. It should be pinned for all-time by the internet.
The 2:90 is some beast! I've taken to constructing my sound around having all the voices enabled (Deep, Modern and Half-Drive). I only recently started on the Half-Drive setting and really like it. I haven't really looked at replacing the Class A tubes with EL34s, but I'm sure I will, all in good time.
The thing that I've struggled with the most is effects placement. I've chopped and changed with having the TC Gmaj2 in the Triaxis FX loop or (as it is now) having it "between" the Triaxis and the 2:90. So to repeat several other forum users:
- 6. Design your equipment, placement of effects and tone around what you hear and not what you read/know.
Last but not least, a call to Mesa: the Triaxis and 2:90 are wonderful amps - there is some smug joy in knowing that my amp is so versatile and tone-full but is not using digital modeling in any way. However, as has been called for many times in this board, they could do with a successor. I really hope that you guys have this in development and that we can see them very soon.
Anyways, that's all for now and I hope this is of use to someone/anyone.
