Diamond Pedals Vibrato

From the listing

Seller's description

The original Diamond Vibrato came out in late 2006 and earned a reputation quickly - a fully analog, true-pitch vibrato built around the MN3007 bucket brigade chip, the same delay line responsible for a lot of the modulation sounds players associate with the late '70s and '80s. It went out of production, prices on the used market climbed accordingly, and players who had one tended to keep them. The new version is back in current production, redesigned around two decades of player feedback and shrunk down to a pedalboard-friendly enclosure without compromising the analog signal path. The MN3007 voicing. This is what the pedal lives and dies on. The MN3007 produces a vibrato with a rounded, slightly liquid texture - organic warble rather than the precise digital pitch shift of modern modulation pedals. It's the difference between a vibrato that feels like it's interacting with your signal and one that sounds like it's processing it. Compandor circuit. Borrowed from the Memory Lane Jr., the compandor handles dynamics on the way in and out of the BBD line - adding warmth and reducing the noise floor that BBD circuits are otherwise prone to. The updated design is pre-trimmed, which means it won't drift out of calibration over the pedal's lifetime. Voltage as a tone control. This is the feature worth understanding. The pedal accepts 9V to 18V and the clock frequency shifts with the supplied voltage, so the same depth and rate settings sound meaningfully different depending on how you power it. 18V delivers the classic, pristine voicing of the original big-box version with the most headroom. 9V adds color and warble - comparable to the "High Mode" on the original. 12V or 15V (via something like a Cioks supply) split the difference. None of these are wrong; they're four different voices in one pedal. Build details. Dual stacked PCBs isolate the audio path from the power and switching circuits. Top jacks, soft-touch true bypass, and a 9–18VDC center-negative input with polar
