Dusk by Dr. Scientist Sounds
Dusk is a digitally controlled analog filter. At its heart is an analog 24dB/Octave low pass filter based around an old-school integrated circuit called an Operational Transconductance Amplifier or OTA. The OTA runs off of split +/-9V rails for great audio quality and a deep filter sound. The digital side brings a whole bunch of convenient and powerful features like controlling the filter setting, tap tempo, MIDI, 6 LFOs, and a platform for all the best filter modes in one small pedal.

No.1 is the original KHDK Overdrive. Powered by our unique proprietary circuit, the No.1 was born from years of passion and sweat, experimenting and tweaking with the tones we heard, loved and set out to perfect.
As versatile as it is bold, the No.1 is designed in the spirit of an overdriven tube amp. It features two gain controls which cascade the gain stages for a rich and harmonic overdrive. Gain one controls the first gain stage from a pure clean boost to a naturally compressing overdrive. Gain two shares one knob with the Bass control. It cleverly controls the gain and the low end of the next gain stage, which adds rich harmonics, bottom end and natural tube-like saturation to your tone. It is designed as an active high-pass filter for the second gain stage and will allow you to set the amount of bottom end with precision.
Made in the USA.
The Cosmichorus doesn't stop at giving you an incredible array of chorus sounds though... Dr. Scientist insists you have an incredible amount of control over the sounds too!Made in Canada
Oh, the Soda Meiser. It's more than just a punny name. For starters, there is a lovely warm and intricate low(er) gain fuzz tone. Great for turning gentle strumming into walls of harmonically dense sound. Turning the gain up will gradually introduce more upper harmonic accents until you are wrangling an upper-octave fuzz beast that's trying to get away from you. Even better! Now the chaos switch is standard! Flip it up to enter the realm of fuzz danger where up is down and rabbits eat dogs.
Conceived in the dark depths of Kirk Hammett’s mind and forged in the secret laboratories of KHDK, an iconic circuit has been perfected to achieve its full potential and create the ultimate tone, with all the control in your hands.
