Expression control over tremolo pedals are the source of my new GAS. I've always had my eye on the Flint, but my positive experience with the MF Ring has me considering the MF Trem, which I know can get pretty damn fast. The EQD Hummingbird may even be faster but the exp. jack is on the side and I have pedalboard real estate concerns. I can't seem to find any demos of the Flint that show how fast the tremolo can get with an exp. pedal. With the MF Trem, the exp. pedal can go beyond what the knobs can do. Can the Flint do this? Is the Flint with the speed knob all the way clockwise the fastest it'll ever be able to go? Any words/thoughts/advice would be greatly appreciated.
