A/DA® STD-1 Stereo Tapped Delay
Transform ordinary signals into
Released in 1980, the A/DA STD-1 Stereo Tapped Delay is a unique analog effects processor with powerful creative features. With its array of six bucket-brigade delays, LFO and modulation controls, and flexible panning, it’s famous for transforming and widening guitars, vocals, drums, and more.
Developed by Brainworx and endorsed by A/DA, the A/DA STD-1 Stereo Tapped Delay plug-in is an exacting emulation of the rare analog rack unit, exclusively for UAD-2 hardware and Apollo interfaces.
Add width, depth, and character to any source with a unique analog, bucket-brigade delay circuit
Build rich soundscapes and unique spatial effects
Layer vocal tracks with highly tunable doubling and chorus effects
Transform ordinary mono tracks into huge, wide stereo sounds

A Hit with Guitarists
Although it works wonders on all types of signals, in the rack-obsessed late ’80s/early ’90s, guitarists revered the A/DA STD-1’s versatile, ultra-analog delay/modulation tones. Jimmie Vaughan’s used it for faux-Leslie warble, while Allan Holdsworth obsessively tweaked two A/DA STD-1’s for complex modulation that went way beyond traditional chorus. Other STD-1 aficionados included Kirk Hammett, Scott Henderson, Steve Khan, and Bill Connors.
Creativity on Tap
The heart of the A/DA STD-1 is its six tunable, non-harmonic bucket-brigade delays. Set the delay time and each successive tap is automatically adjusted to an offsetting value — letting you create echoes and short reverbs with rhythmically overlapping taps. Control the stereo image over time by routing each tap independently to the left or right channel, or add sonic interest by dialing in feedback with the flexible Regeneration section.
Key to the A/DA STD-1’s powerful sonics is its dual LFO circuit with an adjustable sweep rate. Use it to modulate the delayed signal to create warm, three-dimensional layering effects or a uniquely wide soundstage. From classic chorusing and flanging to otherworldly sound design, the A/DA STD-1 is a valuable tool, able to transform any signal into something extraordinary.

unique delay tone
This has a completely different tone and sound than pretty much anything else. I also really like the delay taps it lets you get a alost bouncy effect when dialed in right.Read More

Great time and space plugin
Dont' expect hi-fi there, it's the dirt. But the nice dirt, really helpful to get a synth in the stereo field or get the drums crazy dubbed out.
but you can get it at Plugin Alliance on sale for 1/6 of this price so it gets only 3 stars

Mono compatibility test: PASSED
I really needed something that could create a widening effect without creating dips in the frequency response (like a comb-filtering effect typical of phased / flanged traks).
Most of today pluging try to impress you by creating a large stereo field out of nowhere, but then if you sum the output to mono it has a weird side-effect: the "body" is completely lost due to the phasing of the delayed mid-low range; the transient details are lost because of the doubling effect and the frequency overlaps.
With the A/DA STD-1, instead, I was able to get perfect widening effects without losing mono compatibility, also with the help of the intelligent built-in modulation chain.
Perfect for that old school funky sounds. Just put the delays in the right 3dimensional spot.
You guys Nailed It!!
I have owned several of these over the years, my first unit actually came to the studio I worked at. A/DA sent us a loner rack of all of their products at the time with the STD-1 being among them. I remember dreaming of having two of them to create a Quad guitar rig!! Hey it was the 80's and all the different rack gear being made was full of endless possibilities for processing sound!!
Well I never did own two of these at one time because they were pricy!! I think I paid around $700 for the first one I owned.Now in plug form we get stereo with the press of a button I remember the units came with a front panel diagram to save presets. Back then it was a pencil and a piece of paper! The trick to the STD-1 is you have to be patient and move the knobs in small increments because all of the parameters are interactive and sometimes just a minute change will dramatically cause you to stumble onto an amazing setting!! Thats when I'd bust out the pencil and document it. Of course now all's we have to do is give it a name and hit save!
I'm just blown away by all of the U-Audio plug-ins. While you guys have chosen some of the greatest outboard gear ever made and you are close to reissuing most of it...there are still some great ones left that haven't become plug-ins yet!! How about the PCM-42? The Song Bird Tri-Chorus? The Inovonics 201 Compressor? The Alan Smart C-2? The Ursa Major Space Station!!! And I could go on and on...but I'm pretty sure you guys are cooking up some cool things based on what you've done so far! Please keep up the great work and thanks for bringing the STD-1 back to life : )
Need to study the use of methods
Between the AD/A STD-1 and the EP34, I have superb sounding delay effects covered. TOP marks UA!
Now, if you could model the Dyno My Piano chorus (or the current version by Fulltone - That 80s Chorus) that would be fantastic!
An essential Plugin to get analog feeling
Using it in subtle ways on every channel songs get wider and get a analog feeling, that I could not reach bevore with any other plugin chain. The fine detunings sound natural and the ear does not recognize modulation patterns. It can also be used to put tracks into another dimention to get sounds separated from each other. For me it became an essential plugin to get analog Sound.
Really cool effects plug-in... simply fun to use.
