The Tate FX Sirens Scream is a distortion pedal built around three control knobs and a clipping selection switch, which RockBoard's PedalPedia describes as a hugely versatile way to shape your tone from mid gain crunch to fuzz-like territory1. Because the clipping switch changes the core character of the drive rather than just its amount, it covers ground you would otherwise need separate overdrive and distortion pedals for.
The controls and clipping switch
The three knobs shape the tone across the pedal's range, and the clipping switch is the feature that sets the Sirens Scream apart. It selects what actually clips the signal inside the circuit, and each of its three positions gives a different kind of drive1.
| Switch position | Clipping type | Character |
|---|---|---|
| Left | Silicon diode clipping | Compressed, smooth and full of gain1 |
| Middle | No clipping diodes | An amazingly loud, open overdrive tone1 |
| Right | LED clipping | Loud and crunchy, described as the perfect heavy drive tone1 |
The middle position is worth noting: with no clipping diodes in the signal path, the pedal behaves more like a loud, open overdrive, while the silicon and LED positions give the more compressed, heavier distortion sounds players usually expect from a distortion pedal1.
Power and specifications
The Sirens Scream runs on a standard 9V DC center negative supply and draws 20 mA, so it sits comfortably alongside typical pedals on a daisy-chained or isolated supply1. The circuit is analog throughout1. Like all Tate FX pedals, RockBoard's PedalPedia states it features the best components and switches1.
An English manual for the pedal is available as a PDF from the maker1.
