The Moog MF Trem is a versatile all analog tremolo armed with a variety of waveforms and speeds which can be sped up or slowed down by an expression pedal. Moog gives their Minifooger Trem a powerful shape control that allow you to determine the rise and fall time of the waveform. At the midpoint, you get a smooth optical style waveform that is ideal for just about any musical style. To the right, you will notice a quicker attack and slow fall time while the left direction produces a slow rise and abrupt cutoff. With all these shapes, you can dial in a hard chop, a bluesy rhythm with that lopsided feel and even reverse guitar effects. Once you find your favorite waveform, you can tweak just the Tremolo tone to make it stand out affect just the low end. Plus, you can adjust the overall strength and mix of the effect with the depth control.
