Description

Spread the love

The Epoch Bias Preamp pedal expands upon the original Ep-3 Echoplex that was responsible for defining generations of rock ‘n’ roll tone. Catalinbread has innovated the pedal with a few impactful adjustments like the Bias Control, allowing you to alter the base gain and body of the 3-band EQ, adding an organic boost to your tone. Experience tone-shaping abilities that have spanned generations and genres.

Key Features

EP-3 Inspired – Building upon the classic Echoplex circuit, Catlinbread have gone one step further by combining the iconic circuit with new additions like a boost and filter controls.
Subtlely Control Your Tone – Catlinbread’s enhancements allow you to refine your tone even further than before, giving you sweet subtle filtration, or encompassing gain.

Preamp EP-3

The Volume knob acts in the same way as the original EP-3 – at its core it is a wet-dry mix controlling the space between ‘nothing’ and the preamp itself. Acting as a volume control until dialled at noon, you’ll notice going beyond that you’ll experience subtle frequency enhancements thanks to the loading simulation circuit.

Bias Control

Allowing you to dial in the hot or cold circuit, this knob gives you variation in gain from the preamp, think of it as a gain enhancer with a snap, crackle, and pop effect.

Filter and Boost Controls

If you want even more gain and volume from the preamp circuit, the Epoch Bias has got your back. The Boost knob is one of the improvements Catalinbread has made to the original EP-3 Echoplex, quite simply it acts as a boost when dialled up, but dialled down, you have a simulated EP-3 pure circuit.

The Filter control adds a tastefully gentle hi-cut filter that exaggerates little differences for a more refined, bluesier tone that sounds great no matter how much of everything else you have on the go.

EQ

While Ed Sheeran primarily relies on the natural sound of his acoustic guitar and vocals, he occasionally uses EQ (Equalization) to shape and enhance his tone during live performances or in the studio. EQ pedals or onboard preamps can allow him to adjust the frequency response of his guitar signal to suit the acoustics of different venues or to achieve specific tonal characteristics. Here’s how EQ might be utilized in Ed Sheeran’s setup:

1. **Tonal Shaping**: EQ can be used to adjust the balance of frequencies in the guitar signal, allowing Ed Sheeran to shape his tone to his liking. For example, he might boost the midrange frequencies to bring out the warmth and presence of his acoustic guitar, or cut certain frequencies to reduce any harshness or mud in the sound.

2. **Feedback Control**: In a live setting, EQ can help control feedback by notching out problematic frequencies that might cause the guitar signal to feed back through the amplification system. This can be particularly useful when performing in venues with challenging acoustics or high volume levels.

3. **Room Correction**: In situations where the venue’s acoustics are less than ideal, EQ can be used to compensate for any deficiencies in the sound. By adjusting the EQ settings, Ed Sheeran can tailor the guitar tone to sound more balanced and natural, regardless of the room’s acoustic properties.

4. **Matching Gear**: EQ can also be used to match the tone of Ed Sheeran’s guitar to the sound of other instruments or equipment in his setup. For example, he might adjust the EQ to complement the tonal characteristics of his vocal microphone or to blend seamlessly with backing tracks or other instruments.

Overall, while EQ may not be a central component of Ed Sheeran’s guitar effects setup, it can still play a valuable role in shaping his tone and ensuring that he achieves the desired sound in different performance environments. Whether used subtly for tonal shaping or more aggressively for feedback control, EQ allows Ed Sheeran to tailor his guitar tone to suit his musical vision and performance needs.

Preamp

A preamp pedal shapes and boosts your guitar’s signal before it reaches your amp or recording interface, giving you control over tone, gain, and headroom. It acts as the first stage of amplification, adding warmth, clarity, and character while preparing your signal for the next part of the chain. Some preamps emulate the response of classic valve circuits, while others offer clean, transparent tone shaping ideal for acoustic instruments or direct recording setups.

Used on its own, a preamp pedal can serve as the foundation of your tone, providing a consistent core sound wherever you play. When combined with other effects, it enhances dynamics and helps each pedal sound more defined and natural. Whether you’re looking to push your amp harder, bring life to a dull signal, or refine your sound for the studio, a good preamp pedal adds presence, punch, and musicality to any rig.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.

£455.87

Preamp: Famous for making your guitar sound better even when the echoes are turned off. Quality of repeats: The Echoplex was not necessarily 'hi-fi'. As the echoes repeated, the signal got progressively degraded, losing low end and gaining a shiny, percussive top end with a bit of grit. Record level: There’s a control on the EP-3 that sets how hard the tape gets hit. Wow and flutter: The Belle Epoch’s modulation control was designed to simulate the daily mechanical irregularities inherent in original Echoplex units. Head drag: The original unit had a unique quality that when moving the delay time slider it took a moment to catch up to the adjustment, creating a doppler like effect.
