The Diamond Vibrato is a dedicated pitch vibrato design using bucket brigade analog delay technology, along with an output stereo autopanner (tremolo in mono) stage. This combination of true pitch vibrato with 'faux vibrato' trem/ stereo panning - with LFO speeds either independent or linkable between the stages - allows for creative soundscapes of pitch and amplitude modulation. Expression control for vibrato depth, vibrato speed and autopan speed. Sophisticated relay mode switching allows fast footswitching between vibrato, trem / pan, and vibrato + trem/pan modes. Mono and stereo true bypass operation. Extended headroom 15V internal voltage rail operation. NOS MN3007 bucket brigade delay chips used for pitch vibrato, with a precision high-fidelity trem/autopan output stage.

First Vibrato samples are here! So far, we only have just a small sampling of the many different effect variations the Vibrato is capable of, many more to come. All samples below have both the pitch vibrato and autopan active, we'll be adding more soon to demonstrate the pitch vibrato on its own, autopan on its own, and tremolo (mono operation) on its own. Also to come are demonstrations of the various expression pedal controls.

2-D Staccato: American Std Strat into the Vibrato, with the autopan LFO independent of the pitch LFO. Light pitch modulation, but fairly deep autopanning.

Creepshow: American Std Strat into the Vibrato, with the autopan LFO linked 1:1 with the pitch LFO. Pitch modulation is fairly deep here.

Funky Chicken: American Std Strat into the Vibrato, with the autopan LFO linked 1:2 (autopan is going half the rate) with the pitch LFO. Pitch modulation is fairly deep here too.

Swirl-o-burst: American Std Strat into a Fireburst then Vibrato, with the autopan independent of the pitch LFO. Light pitch modulation, but fairly deep autopanning.

Heavy Weather: American Std Strat into the Vibrato, with the autopan LFO linked 1:1 to the pitch LFO. Deep pitch modulation and autopanning.

The next two samples demonstrate how changing the depth of the autopan completely changes the sound of the overall effect...

MinorKeyLight: American Std Strat into the Vibrato, with the autopan LFO linked 1:1 to the pitch LFO. Deep pitch modulation and light autopanning.

MinorKeyDeep: American Std Strat into the Vibrato, with the autopan LFO linked 1:1 to the pitch LFO. Deep pitch modulation and deep autopanning.

All samples above have the left channel out to a Fender custom shop reissue '64 Vibroverb, and right channel taken out to a Fender reissue Bassman LTD. Both channels were mic'd with an SM57, and recorded through an API 3124+ mic preamp to an Alesis HD24XR. No additional EQ'ing or compression was performed on the sound files.

Here's a block diagram of the Vibrato (true bypass and effect selection control circuitry are omitted for clarity in the diagram below, but each of the vibrato and trem/pan sections can be independently selected with the other true-bypassed, or both can used in series, just by toggling through with the right side footswitch). The 'CMP' and 'EXP' blocks are NE570N noise reduction companding (also used in the Memory Lane and Halo Chorus) used to reduce perceptible hiss from the bucket brigade section.

For fun, here are some pics of the guts of the prototype Vibrato we used for the above samples. Ugly! The production Vibrato will fortunately have a bit less 'character'...

Check out the rewired IC... LOL...

Diamond Vibrato Features:

- dedicated true pitch vibrato using MN3007 analog bucket brigade design
- 'faux vibrato' opto-based autopan (stereo) / tremolo (mono) output stage 
- dual independent LFO's for vibrato and autopan, with selectable 'LINK' control that synchronizes the autopan speed to the vibrato LFO (in vibrato:autopan speed ratios of 1:1, 1:1/2, 1:1/4, 1:1/8, and 1:1/16)
- 'magic-eye' bi-color LED shows both vibrato and autopan LFO rates
- mode footswitch toggles between vibrato, autopan, and vibrato+autopan configurations, with true bypass operation in all modes using relay switching
- ultrasmooth sinewave LFO
- extended headroom internal 15V rails, can be operated from guitar and FX loop levels
- all analog circuitry with VIshay JFET's, Burr-Brown audiophile opamps and Panasonic polyprop caps in the signal path
- mono, and mono in / stereo out operation
- mono input signal directly passed through to both outputs on bypass
- expression pedal control of vibrato depth, allowing the player to manually swell the vibrato effect without changing overall volume
- expression pedal control of vibrato and autopan speed
- telecom grade relay switched true bypass operation
- internally regulated to 15V, can be run from provided 24V adapter or from 18V pedal board power supply outputs (including Y-cable powering from 2 9V outputs on the Voodoo Labs Pedal Power 2 Plus)
- genuine Hammond cast aluminium 7.4 x 4.7 x 1.3 inch case
