Dusk is a digitally controlled analog filter. At its heart is an analog 12dB/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.

The Mini Reverberator by Dr. Scientist loads nine different reverbs into one compact box. This incredible sounding stompbox takes an all analog dry signal, 24-bit A/D/A conversion, and adjustable decay time to the plate and does it so well. The Mini Reverberator features three plates, three rooms, two halls, and a rotary speaker setting that will let any reverb fan sit and meddle for days on end sans repeating a sound. The dry signal stays analog from input to output and is adjustable using the Mix control, so your instrument’s base tone is never modified or colored.
