Asheville Music Tools ADG-1 - Analog Delay - Special Black
$ 397.00
**** IMPORTANT UPDATE ****
Cottonwood Music Emporium will donate 100% of all profits from the sale of Asheville Music Tools effects to charities to support the Hurricane Helene relief. We will donate the monies to BeLoved Asheville - https://www.belovedasheville.com, a charity that Asheville Music Tools also supports.
We have recently purchased all of the remaining Asheville Music Tools inventory in an effort to help support the Western North Carolina communities.
Why are we doing this? Many of you don't know this but Cottonwood Music Emporium was founded in Charlotte, North Carolina where I lived there for nearly 25 years.&; The North Carolina people are special, the area is beautiful and the mountain regions are one-of-a-kind.
***************************
The ADG-1 is the latest installment in Hawker’s legacy of highly sought-after analog delay designs. Utilizing a pair of Xvive™ high voltage BBDs, this delay features up to 700ms of harmonically rich, perfectly floating echoes with an extensive and fully analog control set unprecedented for a pedal of its size. From a bright country slapback to washy dotted eight leads to psychedelic modulated odysseys, the ADG-1 is the new standard in compact analog delays.
Technical Details
The ADG-1 includes over 400 carefully selected components. The entire signal chain utilizes premium audio-grade op amps and high-tolerance, non-microphonic capacitors to guarantee high performance, temperature stability, and low noise.
We began with a classic delay architecture using a pair of studio grade Xvive™ MN3005 reissue Bucket Brigade Devices (BBDs) and a high voltage step-up power supply for maximum headroom. We implemented a tightly calibrated vintage-style compander and incredibly deep, discrete transistor, 5th-order anti-aliasing and reconstruction filters to provide a familiar character with superior clarity, noise reduction and dynamic feel. Our feedback circuit uses a voltage-controlled transconductance amplifier, which provides Hawker’s classic feedback tone while offering the most accurate method for dialing in infinite repeats without runaway or for achieving total feedback overload.
The input preamplifier is critical to the sound of any analog effect. A discrete, high impedance, JFET input stage provides consistent operation across all sound sources and can be used as an always-on buffer. The preamplifier and drive circuit can be used to overdrive the delay line and mixer section for unique artifacts and character that only an analog delay can provide.
We spared no opportunity for flexible control while maintaining a completely analog circuit. The clock generation, modulation oscillator, and even the switching logic are all fully analog in nature. Our clock VCO, with temperature compensated exponentiator, drives the BBDs at extremely high current to eliminate artifacts and provide for a clearer sound. An assignable Expression/CV input expands the flexibility to the limits of user creativity: use an expression pedal to warp the delay time, swell in self-oscillating feedback, or add a modulated vibrato flourish in real time.
An effect of this complexity depends entirely on its power supply and input protection. We took every measure possible to eliminate sources of noise and radio frequency interference (RFI/EMI), as well as protect from electrostatic discharge (ESD) spikes to ensure carefree operation in any studio or performance environment. Our step-up high voltage power supply operates in the MHz range, well beyond the audio band and most other pedals. All voltage sources are highly filtered to eliminate noise and crosstalk between the BBD clock, LFO, and other sections with a multi layer PCB utilizing dedicated split power and ground planes. The power input is fully protected from reverse polarity and over-voltage conditions.
