Universal Audio has introduced an exciting new plugin to their renowned UAD2 DSP system: the EP34 Tape Echo, a meticulously crafted software recreation of the iconic Echoplex tape delay unit. The original Echoplex, particularly the EP3 and EP4 models, has long been a favorite among guitarists and audio engineers for its warm, analog delay characteristics. Now, with the EP34 plugin, users can bring this legendary sound into their DAW with all the tonal richness and vintage vibe of the hardware unit, enhanced with the flexibility of a modern plugin.
The EP34 plugin models both the EP3 and EP4 versions of the Echoplex, which were known for their solid-state designs. Universal Audio has captured the essence of these units, incorporating their signature elements such as wow and flutter, input clipping, and the ability to self-oscillate, which allows users to push the delay into chaotic, musical feedback loops. These features make the EP34 plugin a must-have for anyone seeking authentic analog delay tones with the convenience of software.
Unlike other tape delay units where delay time is controlled by adjusting the tape speed, the Echoplex (and by extension, the EP34 plugin) achieves this by altering the distance between the record and playback heads. This unique method of creating delays gives the EP34 its characteristic sound, with delay times that can be continuously varied between 80ms and 700ms. Users can manually control the delay time via the plugin’s interface, or, when operating in Sync mode, delay times can be set to precise musical intervals, from a 64th note to half a beat, making it easy to integrate the EP34 into tempo-based projects.
To further customize the delay effect, the plugin offers a range of controls for adjusting the number of repeats and their volume. Additionally, a two-band EQ allows users to shape the tone of the delays, whether they want a bright, cutting delay or a darker, more subdued echo. The Recording Volume control can be used to distort the input signal, giving users the option to add overdrive effects to their audio, even if the delays are muted. This makes the EP34 plugin versatile, as it can serve both as a delay unit and as a standalone distortion effect.
On the left-hand side of the plugin’s user interface, several switches provide further tonal flexibility. The Input Hi/Lo switch lets users choose between emulating either the mic or line input of the original Echoplex, allowing for additional control over the input signal and making it possible to overdrive the delay even more. There’s also a Tension Hi/Lo switch, which replicates the different tape tensions that could be adjusted on the original hardware. The effect of this switch is especially noticeable when adjusting the record head slider in real time. In the high-tension setting, the delay time and pitch shift occur more slowly, while in the low-tension setting, these changes happen more rapidly, providing a wider range of sonic possibilities.
The plugin also includes a Wet On/Off switch, which removes the dry signal when set to “On,” making the EP34 ideal for use as a send effect. This is particularly useful in modern mixing environments where sending a signal to a dedicated effect bus is a common practice. Additionally, the Send On/Off switch disables the signal input, allowing users to employ the EP34 plugin as a sound-generating tool by using its self-oscillation capabilities. According to Universal Audio, this mode allows the plugin to be used as “an instrument that can be played by manipulating the controls while in chaotic oscillation,” offering endless creative potential for experimental sound design.
The Echo Pan knob provides control over the stereo placement of the delays, allowing users to position their echoes anywhere within the stereo field. This, combined with the plugin’s other features, gives users full control over the spatial dimension of their delays, making it easier than ever to create immersive, dynamic soundscapes.
While the DSP usage of the EP34 plugin is relatively high, requiring about a third of a UAD2 Solo card to run, it remains less power-consuming than some of Universal Audio’s more demanding plugins, such as the Massive Passive. This means that users can enjoy the EP34’s rich, detailed sound without overwhelming their system’s resources. The plugin’s power consumption is well worth the stunning sound quality it delivers, and its ability to faithfully recreate the beloved sound of the Echoplex tape delay.
Available now through Universal Audio’s online shop for $199, the EP34 Tape Echo plugin is an essential tool for anyone looking to capture the vintage warmth and character of the original Echoplex in their digital setup. Whether you’re a guitarist, producer, or sound designer, this plugin offers a rich, analog delay experience that will elevate your productions to new heights. If you’re seeking authentic tape echo tones with modern flexibility, the EP34 plugin is a perfect addition to your arsenal.
