Formula B That Screamer

A Classic Revisited: The "Screamer" Spirit in a Handcrafted Version

The Formula B That Screamer continues the legacy of overdrives that have defined decades of guitar tones, from punchy blues rhythms to singing rock leads and fusion. The idea is not to reinvent the formula but to elevate it to a level of finish and coherence worthy of a modern pedalboard: selected components, low noise floor, and above all, a playing feel that remains organic. Its circuit notably relies on an original JRC4558D dual op-amp, an iconic choice to capture the warmth and musical compression that define the genre's signature sound.

Who It's For, Which Styles, and In What Contexts?

This overdrive is aimed at guitarists who want a simple-to-adjust pedal capable of covering a wide range. In blues and rock, it delivers that midrange bite that helps the guitar cut through the mix while maintaining a flexible feel under the fingers. In fusion or more technical playing, it provides a clean, controlled gain foundation, ideal for precise phrases without unnecessary harshness.

Practically, the That Screamer works equally well as a primary overdrive on a clean channel or as an amp boost to push an already crunchy channel. It also excels stacked with other pedals (fuzz, distortion, other overdrives): its mid-focused EQ tightens the lows, smooths the attack, and yields more present leads, both in studio and live settings.

Controls, Modes, and Design: Efficiency for Fine Tuning

The pedal offers a trio of immediately familiar controls: Drive for gain amount and compression, Tone to adjust the overall balance (from warm to sharp), and Level to precisely set your output volume (a key point when boosting an amp or balancing multiple gain stages on the same pedalboard). The range goes from a light crunch that's very responsive to a medium saturation ideal for solos and articulated rhythms.

For further customization, internal adjustments (accessible by removing the back plate) allow you to tailor the voicing to your guitar, amp, and playing style via 4 modes : T808 (classic vintage mid hump), T9 (more open and aggressive), T10 (more modern and tight), and Hybrid Mode (a blend of T808 and T10). This is a real advantage if you switch from a vintage-style combo to a modern head, or alternate between single-coils and humbuckers.

Regarding signal integrity, the That Screamer features a true bypass with buffer, designed to maintain a clear attack and consistent feel, especially on long signal chains or dense pedalboards. The entire unit is handmade in Todi, Italy, with particular attention to robustness and consistency from one unit to another.

The Sound

The That Screamer delivers an overdrive with a creamy and musical character, focusing on the midrange to help the guitar "speak" without artificially boosting the lows. The dynamics remain central to the playing experience: lowering the guitar volume cleans up the saturation with a smooth transition, handy for moving from a near-clean accompaniment to a denser lead without adjusting settings. Depending on the chosen internal mode, you can go from a very "vintage" and singing texture to a tighter, more modern sound, useful for maintaining definition on chords or more pronounced rhythms.
