Thanks for the review, Ben.
GT1000FX is IMO an important part of the equation. I have it paired with a Zilla Fatboy 2x12. Hi gain chugga chugga glory, but a cab is not so versatile for cleaner tones.
Other (mediocre amps) I have tried are: Behringer A500, EHX Magnum 44.
GT1000FX is unveiled high definition in your face in comparison. No contest.
