Just listen to what the Skychord Cloudbuster does to a Juno-6 at around the 1:35 mark in the video above. It detunes the synth in a modulating say Clockwork Orange soundtrack type of way. Add a little of it’s Pre-amp gain and you have a scary vintage sounding distortion unit. So many little boxes of want lately. This one is $375 USD.
“The cloudbuster is a sequentially modulated lo-fi echo machine featuring harmonically dark burned out lightning strike repeats, howling gore ripping feedback, nightmare time based gurgling, and heavenly comatose modulations. At the heart of the cloudbuster is a four stage sequencer that modulates the delay time via a sequencer. This sequencer has a length of 2 or 4 steps.” – skychord.com
