So, I posted a thread about the Matrix XT800 power amp that I tried with my Axe-FX. I A/Bd it with my VHT 2:50:2 and it was pretty good. i wasnt sure if I wanted to let the VHt go though. Anyway, myself and a few other users had some input with Matrix and a tweeked version was produced - named the GT800FX. This had a lower fan noise, lowe input impedance, tweeks to the high and Low Freq damping, and inclusion of combi ins (Jack/XLR) and combi outs (Jack/Speakons) as standard. The first 30 went out a couple of weeks ago and reviews have been generally glowing. Well, a couple of guys got together in California to comapre the VHT 2:90:2 with the GT800FX. Surprising result !! Read that review here: http://forum.fractalaudio.com/amps-cabs/36741-amp-shootout-matrix-gt800fx-vs-vht-2-90-2-a.html And also the original thread on the development of the GT, along with comparrisons and reviews from the first owners here: http://forum.fractalaudio.com/amps-cabs/33726-new-matrix-gt800fx-amp-axe-fx.html Ive posted it here, because this amp is just as viable for ownersof other modellers. Rack users would benefit most - so 11r, GSP1101, Boss GT Pros, Pod Pros etc - though theres no reason why user of floor based units couldnt rack one for use with a cab rather than an amp head.
