You'll love the Seymour Duncan SFX-07 Shape Shifter Tremolo pedal if you like the smooth, easy-to-dial-in sound of vintage amp tremolo. But if you also crave unrestrained versatility, and you want to delve into ultra-modern experimental sounds like flutters, shimmers, warbles, and even radical "helicopter chops," the Shape Shifter is your dream tremolo.
The Shape Shifter pedal's sonically pure, 100% analog signal path delivers the familiar lush, hypnotic, pulsing tremolo vibes characteristic of '50s tube amps. Digital tap control offers incredible control. Shape and Wave controls provide unparalleled versatility.
There are two modes. In Rate mode the tremolo speed varies continuously from one to 20 cycles per second. An LED pulses in time with the tremolo effect for easy Rate setting. In Ratio mode, tapping the Tap Rate switch establishes the speed, allowing for easy synchronization of the tremolo rate and song tempo. Also, in Ratio mode, the tapped tempo can be expressed in your choice of four tap-to-note ratios: 1:1, 2:1, 3:1, or 4:1 (1/4 notes, 1/8 notes, triplets, or 1/16 notes).
The Wave control allows the tremolo effect to go from the smooth modulation of a sine wave through the sharper characteristics of a triangle wave to the abrupt on/off effect of a square wave drive.
Most classic tremolos increase the volume over a certain period of time—say, a quarter of a second—and then decrease the volume over a similar period of time, giving a smooth, even feeling to the tremolo effect. When set to the middle of its range, the Seymour Duncan Shape Shifter's Shape control does exactly that, but 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, 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, adding a very different feel to the tremolo effect. With quick swell and a slow drop, the effect is percussive like a piano. Conversely, with a slow swell and sudden drop, the result is reminiscent of a tape played backwards.

This is a great sounding, trem with a lot of built in flexibility. Although I haven't used the tap function yet, all other features more than meet my expectations. I'm using this one for keyboard work, and it's got a permanent place on my pedalboard. Forget about judging it on price alone........get this one!
Price to performance is right in the sweet spot. Tap tempo was important to me, and this feature is well designed and easy to use while performing. It sounds great. Classic trem sounds are easy to dial in, as are choppy effects, and the shape control allows for a subtle compression effect somewhat like a vintage bias tremolo. It can also get extreme for some inspiring and unusual textures. The case is sturdy, and it's nice to see a true blue 3PDT bypass switch on the inside. It lacks the memory presets and complex subdivisions of the most expensive boutique trems, but for a single great trem sound that you can match to the song tempo, it's excellent. My only minor complaint is the large size, but all the SD dual switch pedals share this form factor, and it would be hard to cram all the controls into a 1590 sized enclosure. Overall, this is a terrific product.
