Alchemy is a stereo BBD (Bucket-brigade device) full analog audio path chorus, featuring six different individual presets and a delay control that sets the center delay time that the LFO modulates around. Behind this gem is the re-issued version of the legendary MN3207 delay chip that produce smooth warm modulation to nauseating detune sounds . Each knob is controlled by a small microprocessor while your guitar signal stays 100% analog and never gets digitally processed. This unique concept allows you to control, save and recall multiple modulated tones instantly.
