Diamond Vibrato

An Analog Vibrato Born to Recapture the Feel of Classic Modulations

Designed at the end of 2006, the Diamond Vibrato had a clear mission: to offer a musical-feeling, analog "true-pitch" vibrato built around the famous MN3007. This BBD (bucket brigade) architecture is at the heart of the modulations that defined many guitar productions of the 70s and 80s, with its unique blend of warmth, depth, and natural micro-irregularities. Today, the Diamond Vibrato returns with improvements and extended power supply versatility, while preserving the organic DNA of the original.

Who Is It For, Which Styles, and In What Playing Context?

The Diamond Vibrato is aimed at guitarists seeking an expressive, lively modulation capable of ranging from subtle shimmer to the most hypnotic oscillations. It excels in blues, rock, indie, pop, psychedelic, as well as ambient and post-rock when combined with delay and reverb.

On a pedalboard, it can be placed either before an overdrive for a "chewy" and textured vibrato, or after distortion pedals to maintain a clearer and more spacious movement. In the studio, it becomes a powerful tool to thicken a mono track, add a "tape" feel, or create controlled detuning effects without falling into caricature.

Controls, Modes, and Design: Modulation Both Vintage and Modern

The core of the pedal relies on an analog BBD MN3007 audio path, complemented by a Compandor circuit (inspired by the Memory Lane Jr) that acts as a compressor/expander. The result: a more "controlled" playing feel, a more consistent response depending on attack, and a significant reduction of the inherent noise from BBD circuits, without sacrificing musicality.

The speed range is particularly wide (from 0.1 Hz to 20 Hz), allowing coverage of slow, deep, cinematic movements as well as fast "warble"-type vibratos. The Chorus control serves as a dry/wet mix: at low settings, you get pure vibrato, and as you increase it, you slide into dense and lush chorus tones. A Jazz selector allows you to fine-tune the tonal balance to adapt the brightness to your guitar and amp.

The speed doubler function (on/off or momentary) is ideal for instantly switching from a calm modulation to a dramatic acceleration, perfect for a chorus, a break, or a very expressive "tape-like" moment. The entire design features stacked PCBs to optimize isolation between audio, power, and switching.

Sound

The Diamond Vibrato stands out with a deep yet defined vibrato, featuring the typically BBD organic texture: the movement seems to breathe, and the modulation maintains a warm character even as speed increases. At 18V, the sound is more open, with greater dynamics and a better sense of headroom, which is especially suitable for high-output pickups and busy effects chains.

At 9V, the pedal tends to add a bit more color and "movement": you get a more characterful modulation, very inspiring for chord parts, slow melodic lines, or controlled lo-fi textures. The Chorus mix finally allows precise sculpting of the direct signal presence, ranging from slight thickening to a wide chorus, without losing your guitar's identity.
