A classic Univibe-inspired sound, completely reworked for the modern pedalboard.
The ThorpyFX ER-2 BLOCK 3 takes the unmistakable movement, pulse and swirl of a classic Univibe and pushes it into a more flexible, compact and highly usable format.
Based on ThorpyFX’s own analog Univibe-style circuit, the BLOCK 3 evolves the earlier ER-2 design with a new Phase switch, allowing you to run the effect either in phase or out of phase. The result is a wider range of vibe and chorus textures, from subtle vintage movement to deep, chewy modulation.
Classic Vibe, Expanded
The goal was simple: capture the feel of the great Univibe sounds heard across decades of classic records, then make the circuit more flexible without losing the immediacy that makes this style of effect so addictive.
Under the hood, the ER-2 BLOCK 3 is a sophisticated pure analog design, but the controls remain straightforward and musical.
Chorus and Vibe Modes
The left footswitch changes the character of the effect:
-
Chorus Mode: classic Univibe-style wet/dry modulation
-
Vibe Mode: outputs the wet signal only for a deeper, more pronounced effect
The right footswitch switches the pedal on and off.
Phase Control
The new Phase switch is one of the key additions to the BLOCK 3. It allows you to choose between in-phase and out-of-phase operation, changing the depth and character of both the vibe and chorus sounds.
This gives you access to a broader range of modulation textures without adding unnecessary complexity.
Controls
Intensity
Controls how much modulation is introduced into your signal, from gentle movement to deep, dramatic swirl.
Offset
Changes the way the LFO ramps and alters the relationship between the wet and dry portions of the sweep. It is a subtle control, but extremely useful for fine-tuning the feel and pulse of the effect.
Speed
Sets the rate of the modulation, from extremely slow movement to fast and intense rotary-style textures.
Volume
Controls the overall output level of the effect, allowing you to compensate for perceived volume changes or push the signal harder.
Phase
Selects whether the vibe operates in phase or out of phase.
Why Buy the ER-2 BLOCK 3?
Because the best vibe pedals don’t just modulate your signal – they make it feel alive.
The ER-2 BLOCK 3 delivers the deep, organic pulse and asymmetrical sweep that players love about vintage Univibe circuits, while adding enough control to make it work in a much wider range of rigs.
From subtle Hendrix-style movement to thick, hypnotic psychedelic swirl, it can cover the classics while still offering something distinctly ThorpyFX.
