You asked for it, and here it is. Over the years we at Catalinbread have listened to customer comments on our original Semaphore, and have combined everything into the ultimate tremolo pedal, the Stereo Semaphore Tap Tremolo. This pedal combines a fantastic audio path, with a diverse tremolo that has a bottomless feature set including 8 different waveforms, tap tempo and divide, stereo outputs, and expression pedal capabilities. It's footprint is ideally suited for the stage, no more missing footswitches or nudging knobs when engaging, and the Stereo Semaphore suits both foot tappers and knob twiddlers in its control.
At the heart of the Stereo Semaphore is a lush audio path that incorporates optically controlled JFET gain stages to sculpt a gorgeous clean boost sound, that is present and alive without being peaky or harsh. We've quadrupled the number of waveforms, everything is in there from classic square, triangle, and sine waves to ramping sounds, and a mind-bending random shape. And in conjunction with the Shape contour, which morphs the waveshape, numerous waveforms are waiting to be unlocked. The Stereo Semaphore sounds fantastic whether you are running it mono or stereo, and the Tap Tempo section is engaging and easy to use. We've even included a control voltage input and output, to slave or master the tap tempo on future Catalinbread pedals with Tap Tempo functions.
The rate control, controls the speed of the tremolo. On the Stereo Semaphore this knob’s characteristics are affected by the position of the Tap Divide control. If the Tap divide is set at a higher rate, you will notice that the Rate knobs sweep will change as well. The expression pedal nullifies the rate control when plugged in.
- Tap Divide
The Tap Divide works as the engine for the Tap function of the Stereo Semaphore. Since a tremolo can obviously operate at a much faster rate than one could tap out, this control takes your tap tempo and multiplies it by the corresponding note beats. The quarter note represents the same tempo that you tap out. Once a tempo has been tapped in, the Tap Divide can function as an in-time rate control.
The Shape control is used to morph the selected waveshape. At noon your waveshape will represent the shape on the Waveshape control, but to either side this shape will slant providing numerous sounds and endless possibilities. The Shape, however, has no effect on the Random waveshape setting, because it is random.
The Waveshape control provides eight different waveshapes, which won’t leave anybody wanting for more.
The Depth control dials in how much tremolo is in your signal. Dialed all the way down, the Stereo Semaphore can be used as a boost, and you can bring up the depth enough for slight shimmers in your signal, or all out depth, for maximum effect.
The Volume control, obviously, controls the volume of the pedal. Unity on the pedal is around noon, depending on the voltage running, and provides plenty of boost or attenuation.
With the original Semaphore we realized that features without benefits are irrelevant, and benefits without features lack credibility. The Stereo Semaphore Tap tremolo offers up everything you need in a tremolo, and nothing you don't.
