Crazy Tube Circuits designed their Memphis Vibrato as the "little brother" to their Killer V. Lots of CTC's customers asked for a true pitch shifting amp-like vibrato pedal, without the drive section — and they delivered.

It features all-analogue LFO and a true-to-the-original-amp 2-stage pitch shifting circuit powered from an internal voltage multiplier for high headroom and improved dynamic response. A clean, period-correct preamp with up to 20db boost takes you back to the late '50s/early '60s!

With the intensity and speed knobs, you can add a subtle shimmer or a pronounced 3D acoustic image and musical feel with ear-pleasing vibrato for instant, classic Lonnie Mack/Robert Ward sounds.

The toggle switch selects between 100% modulated signal, or places the dry unmodulated signal in parallel with the modulated signal. The latter setup was found in some of the original amps through "stereo" inputs and yields whirling phaser/vibe sounds.

Specifications

  • Voltage: 9V DC, centre negative (6F22 type battery or PSU – sold separately)
  • Current Draw: 17mA
  • Made in Greece

Boost

A boost pedal does one simple thing brilliantly — it makes your signal louder, stronger, and more alive. Whether you’re pushing a valve amp into natural breakup, lifting a solo above the band, or adding a touch more presence to your core tone, a clean boost gives you extra headroom without changing your character.

Use it at the front of your chain to drive other pedals harder, or after your gain stages to raise volume without adding distortion. Subtle or powerful, transparent or slightly coloured, a boost is one of the most useful tools on any pedalboard — small box, big difference.

Phaser

A phaser is a type of guitar effects pedal that creates a swirling, sweeping sound by modulating the phase of the audio signal. It works by splitting the incoming signal into two paths, shifting the phase of one path, and then recombining them. This creates peaks and troughs in the frequency spectrum, resulting in a distinctive, “phasing” effect characterized by moving notches in the frequency response.

Here’s how a phaser pedal typically works and some common features:

1. **Rate**: The rate control adjusts the speed at which the phase-shifting effect oscillates. Increasing the rate produces faster modulation, creating a more pronounced swirling effect, while decreasing the rate slows down the modulation for a smoother, more subtle effect.

2. **Depth**: The depth control adjusts the intensity or depth of the phase-shifting effect. Higher depth settings result in more pronounced peaks and troughs in the frequency response, while lower settings produce a more subtle modulation.

3. **Feedback (or Regeneration)**: Some phaser pedals feature a feedback control that determines the amount of modulated signal fed back into the effect. Increasing the feedback creates more pronounced peaks and troughs in the frequency spectrum, resulting in a more intense and resonant phasing effect.

4. **Stages**: Phasers typically have multiple stages (usually four, six, or eight), each of which contributes to the overall phase-shifting effect. More stages generally result in a more complex and textured phasing sound.

5. **Sweep (or Manual)**: The sweep control adjusts the center frequency of the phase-shifting effect. This allows you to focus the phasing effect on specific frequency ranges, altering the tonal character of the modulation.

6. **Resonance (or Feedback)**: Some phaser pedals feature a resonance control that emphasizes the peaks and troughs in the frequency response, creating a more pronounced and resonant effect. This control can add richness and depth to the phasing sound.

Phaser pedals are commonly used in various music genres, including rock, funk, and psychedelic music, to add movement, depth, and texture to guitar tones. They can be used to create swirling, swirling effects on rhythm parts, add dynamics to lead lines, or create atmospheric textures for ambient music. Overall, phaser pedals offer guitarists a versatile tool for shaping their tone and adding expressive modulation effects to their playing.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.

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.

Vibe

A vibe pedal delivers that unmistakable swirling, pulsing modulation inspired by classic late-60s tones. It blends elements of chorus and phase into a deep, throbby movement that feels organic and three-dimensional under your fingers. From subtle shimmer to full psychedelic swirl, vibe adds motion without losing the core of your sound.

Use it to bring warmth and texture to clean chords, add movement to sustained leads, or capture that rich, expressive wobble heard on countless vintage recordings. Smooth, hypnotic, and full of character, a vibe pedal turns simple phrases into something far more atmospheric and alive.

Vibrato

Vibrato refers to a guitar pedal effect that modulates pitch slightly up and down, creating movement and a sense of wobble in the sound. Unlike tremolo, which changes volume, vibrato affects pitch only, producing anything from subtle shimmer to pronounced, warbling textures. It is often used to add character, depth, and vintage-style modulation to guitar tones.
