Bought a G3X just to try digital again. Using an Ibanez TSA15 head & cab for my amp with the G3X between the analog TS and the amp input.
The Zoom's reverbs, delays and modulations are all very good. A lot ogff wacky effects that I won't use as well. The amp models do not sound good into my amp, I have not tried direct into PC speakers yet.
The overdrive and distortion stomps were the ones I was wanting to add some rock tones to the Ibanez amp. the Governor stomp is my favorite and the Overdrive second.
