I also use the Fractal Audio Axe-Fx Ultra amp- and effects-modeling unit, and lots of additional software, including IK Multimedia AmpliTube and Peavey ReValver 3, and soft synths such as Native Instruments’ Reaktor 5 and Absynth 4.
To write a review about all the synth sounds would be way too long. Like that sentence. So I’ll keep it short and sweet, I think Absynth is one of the best synth plugins ever! All those sounds are just awesome.
