I got a new working Axe FX III MK 2 Turbo today from G66 NO FEEDBACK ISSUES AT ALL SOUNDS GODLY! (ended up being the same price as the reverb one after import taxes and stuff so I was stupid for not going straight to G66). I posted a few days ago about a faulty Axe FX if anyone remembers, this device has been accepted for return by Reverb and will be on the way back when it is collected by the couriers. The problem was a noise gate bug and horrific high-pitched undertones that resonated after every sound input. If ANYONE is struggling to get clear high-gain tones out of their Axe FX 3, RETURN IT ASAP, if it doesn't sound like it should out of the box, it CAN'T BE TWEAKED AWAY! I have seen some users go on with the issue for 10 YEARS and fail to get any usable tones!! NO it is not you, NO it is not the guitar, NO it is not your grounding. You didn't get an Axe FX III MK 2 Turbo, you got turbo BULLSHIT! Be smart, don't waste a decades of your life!!!! Please, if a few solutions don't work, follow your gut. Anyway all sorted very happy thank you Fractal.
