Diamond Vibrato Limited Maple Leaf Edition

The Diamond Vibrato Limited Maple Leaf Edition is a limited-run version of Diamond's analog vibrato pedal, a compact effects pedal that modulates the pitch of your guitar signal to produce a wobble or warble. It is built around the MN3007 bucket brigade delay (BBD) chip, the same analog delay-line technology behind the chorus and vibrato sounds of 1970s and 1980s guitar records, and Diamond describes it as an analog, true-pitch vibrato pedal¹. The audio path is 100% analog, with no digital conversion of the signal¹.

Diamond says the MN3007 chip delivers "a natural, liquid-like pitch modulation with a rounded vintage texture and mojo that is missing from modern digital counterparts"¹. The pedal also borrows a compandor circuit (a combined compressor and expander) from Diamond's Memory Lane Jr. delay, which the maker says provides increased clarity and less distortion, and which is pre-trimmed so it never needs recalibration¹.

An analog vibrato built on the MN3007 chip

Vibrato works by continuously varying the pitch of the signal up and down, and a bucket brigade chip does this in the analog domain: the signal is passed along a chain of capacitors, and varying the clock rate that moves it along varies the pitch. The MN3007 is a Panasonic BBD chip that Diamond calls "revered" and "renowned for its ability to create the rich, organic, and warbling Vibrato & Chorus tones which make the sounds of the 70s and 80s guitar icons"¹.

Because the modulation happens in an all-analog path, the pedal sits alongside other BBD-based vibratos rather than DSP-based ones. Players comparing analog vibrato pedals can also look at the Diamond Vibrato, the Diamond Pedals VIB1 Analog Vibrato (compact reissue), and other entries in the vibrato pedals category.

The Limited Maple Leaf Edition is an analog, true-pitch vibrato pedal built around the MN3007 Bucket Brigade Delay chip¹. Diamond describes the chip as the heart of the pedal's vibrato and chorus-style tones, and the design carries a 100% analog audio path in a compact footprint¹. The pedal is made in Canada¹.

Controls and the Jazz switch

The control the maker documents in detail is the Jazz switch, a two-position high roll-off control that shapes how bright the modulated signal is¹.

In the UP position the roll-off sits at 5 kHz, which leaves most of a guitar's upper harmonics intact. In the DOWN position it drops to 1.5 kHz, which cuts a much larger slice of the treble and gives the effect a darker, rounder character, the kind of voicing the "Jazz" name suggests.

Power, switching, and connections

The pedal runs on 9 to 18V DC with a negative tip and a 2.1mm barrel jack, drawing 40mA at 9V and 45mA at 18V¹. Running it at 18V is an option for players who want to hear what the higher headroom does, but the maker does not claim a specific sonic difference between the two voltages.

Switching is relay true bypass with a soft-touch switch, so the signal is fully disconnected when the pedal is bypassed¹. Input impedance is greater than 1 MΩ, which preserves high-end from guitar pickups, and output impedance is under 10 KΩ, low enough to drive most amp and pedal inputs without tone loss¹.

Where it is made and warranty

The Limited Maple Leaf Edition is made in Canada¹. Diamond covers all of its products, including those bought through the diamondpedals.com website or its authorized dealers, with a three-year warranty against failure resulting from defective parts or faulty workmanship¹.
