Shape Shifting

By now you’ve figured out that the SFX-07Tremolo can do classic trem beautifully. But it can do more—a lot more.The key to many of the SFX-07’s most unique effects lies in the Shape control. So what does this knob do anyway? We’re glad you asked . . .

Most tremolos increase the volume over a certain period of time (say, a quarter of a second) and then decrease the volume over the same period of time. This gives a smooth, even feel to the tremolo effect. When set to the middle of its range, the Shape control on the SFX-07Tremolo does exactly that.

But here’s where things get interesting. When the Shape control is rotated away from its center position, the relationship between the time spent increasing the volume and the time spent reducing the volume changes. For example, instead of a quarter of a second of volume increase followed by a quarter of a second of volume decrease (for a total time of a half second for a full tremolo cycle), you can dial in one-tenth of a second of volume increase followed by four-tenths of a second of volume decrease, or vice-versa. This adds a very different feel to the tremolo effect. From slightly skewed to one direction or another, to an instant rise or fall time, the tremolo effect now offers more than just a simple pulse. Plus, we found that with various vintage tremolo devices, during the rise and fall, the actual tremolo function can pull and sag voltage back and forth.The current draw and release can subtly affect the audible rise and fall times, creating a waveform that isn’t perfectly symmetrical. At extreme settings, with a fast swell and a slow drop in volume, the effect is percussive and makes a clean guitar almost sound like a piano. Conversely, with a slow swell and sudden drop, your guitar tone sort of sounds like it’s being played backwards.

Because of its radical nature, this control may take a little getting used to, but if you want to create tones that have never been heard before, the Shape control will be your best friend. Here are some righteous sample settings to get you out of your same-old same-old.
