Three classic Tube Screamers in one!
Formula B’s That Screamer Overdrive Pro 4558 packs the legendary sounds of three iconic Tube Screamers (TS808, TS9, and TS10) into a single, versatile pedal.
This meticulously crafted overdrive is built for players seeking everything from classic midrange crunch to glassy blues tones and subtle low-gain boosts reminiscent of John Mayer’s signature sound.
At the heart of That Screamer lies a careful recreation of the original circuits found in the 1981 TS808, 1982 TS9, and 1986 TS10.
Formula B not only faithfully reproduced these circuits but also enhanced the dynamics and added 5dB of extra output volume.
Inside, you’ll find premium components, including tantalum capacitors, bipolar electrolytic capacitors, and the coveted JRC4558D op-amp paired with rare Japanese-made MA150 clipping diodes—all contributing to its rich, authentic tone.
What sets That Screamer apart is its internal switching system, allowing you to select between the three Screamer voicings.
With two internal switches, you can explore TS808 warmth, TS9’s aggressive bite, or TS10’s unique character—or even combine TS808 and TS10 modes for a distinct tonal blend.
Whether you’re after bluesy breakup, Plexi-like grit, or a clean boost to push your amp, That Screamer has you covered!
