Wow!!! Talk about going off the rails..
Ok lets recap, rather than give visualrocker69 what amp to buy next.
lets see if we can fix this!!!!!!!
1. Does the Triaxis have the gain or tones???
2. I went beck to your first post, and you same the TA Volume is on 1.5 - 2.
I read the manual is says 3 - 7 , not sure about this as I have played with mine. I ended up at 5, this makes a big difference.
Again there are more experienced users here than me, so perhaps they can suggest the best place to start.
Also If you are not use any effects your tone will be dry and you mention you have a G- Major, but are you using any effects yet??
If so that could be the problem.
If not, your sound might be too dry, Reverb and slight delay are a must as they add ambiance to your tone.
Also where are you when you listen to your sound?? as I have found to close to the speaker gives you bad sound quality.
I try for a performance distance 5 - 7 feet away, then a face the same as on stage, not facing my amp.
This might sound silly, but I don't think anyone has covered this **** yet.
Big tip, check your leads, I did a gig last Friday night, I thought It didn't sound right, my gain seem week but worked fine, moved the cable Bam, totally different tone and gain, I mean night and day. It went from Sterile sounding **** to a Awesome sounding amp. I hate cables as you can't tell if there dead or dying.
Anyway, we all trying to help you.
