Seymour Duncan SFX-07 User Manual

For Tone That Sets You Apart

Congratulations SFX-07 Tremolo Pedal™

on your purchase of the

Seymour Duncan

. You can start using your Tremolo right away and you’ll be able to immediately revel in the hypnotic, pulsing, vibey tones that this pedal is capable of. You might want to first read through these instructions in their entirety to gain valuable information that will enhance your enjoyment of your Tremolo.

General Information

Between the 100% pure analog signal path and the digital tempo control, your SFX-07 is a trem like no other trem. Actually, that’s not entirely true, because if you want the kind of tremulation that you know and love from your favorite tube amps, this pedal can do it. But if, in addition to that, you want inspiring and crazy tones that you’ve never heard before, the SFX-07 can do that too. In short, the Shape Shifter begins with the soul of the most musical tremolos of the past 50 years, and takes you places tremolo pedals have never gone before. Your Seymour Duncan stompbox is designed for years of solid performance. From the 16 AWG steel chassis to the studio-grade circuit design, this Tremolo is simply done “right.”

Explanation of Controls

Front Panel (See page 2)

1. Depth – “How much tremolo would you like?” This wide-range

control smoothly varies the tremolo effect from a subtle shimmer to an intense rhythmic pulse.

2. Shape – “When should the rise and fall occur?” This amazing control allows for the variation of tremolo rise and fall time (how fast or slow the volume increases and decreases) for unique percussion and “reverse decay” effects.

3. Wave – “What should the tremolo wave look like?” This continuously variable control takes you from a smooth sine wave of your favorite vintage amps, to a choppier triangular wave to an abrupt on/off pulse square wave.

4. Rate/Ratio Knob – “How fast am I going?” This knob carries two functions. When in “Rate” mode, this knob simply adjusts the rate of the tremolo effect. From one pulse per second to more than twenty per second, this is a continuously variable control. When in “Ratio” Mode, this control takes you through four tempo subdivisions: 1x, 2x, 3x, and 4x, or quarter-notes, eighth-notes, triplets, and sixteenth-notes. This is not a continuous control, but corresponds to the four distinct ratios marked on the outer band.

5. Rate/Ratio Mode Switch – “What will the Rate knob do?” This switch governs how the Rate/Ratio knob operates (see Rate/Ratio Knob description above).

6. Rate/Ratio Indicator – Turns on when in “Ratio mode”.

7. Tap Tempo Footswitch – “Let me set the tempo.” This switch lets you

match the tremolo rate to any song or groove on the fly by simply tapping along in time. Even if you’re in Rate Mode (as selected by the Rate/Ratio Mode Switch), you can override the Rate setting by tapping in a new tempo at any time (the default setting is eighth-notes, or two trem cycles per tap). If you’re in Ratio Mode, entering your tempo on the Tap Tempo Footswitch will default to the rhythmic subdivision the Rate/Ratio knob. For example, when set to 3:1 you can tap in your

tempo and the tremolo pulsations will occur in triplets. (Don’t worry if this sounds confusing—it’s actually really intuitive and fun when you’re plugged in.)

8. Heartbeat LED – “How fast am I going?” In addition to indicating the pedal’s on/off status, this light pulses in time with the tremolo effect for easy Rate setting. The character of the LED also changes to reflect the Wave and Shape settings, for a highly intuitive visual reference.

9. True-Bypass Footswitch – “Get out of my signal path!” Shutting the pedal off removes the circuit from your guitar’s signal chain. This allows your guitar’s signal to pass through the Shape Shifter without affecting your tone or gain. In addition, when bypassed, the processor goes into a sleep mode to preserve battery life.

1. Input Jack – Plug in your guitar signal here. (or if compatible, the send

from your amp’s effects loop)

2. Output Jack – Provides the output signal. Run a cable from this jack to the input of a guitar amp. (or if compatible, the return jack of your amp’s effects loop)

3. Power Jack – This is where you can connect a regulated 9-volt DC adapter (center negative) such as the Seymour Duncan 11802 if you opt not to run the Tremolo on a 9-volt battery.
