From Alexander Pedals:The Amnesia is carefully tweaked to bring back the vintage tone and response of three distinct analog delay units. So strap in - it's about to get murky.Specs:TIME - adjust the delay time from 10ms to 900ms.REPEAT - controls the feedback of the delay.MOD - Adds a luscious modulation to the delay. At 12 o'clock there is no modulation. Clockwise adds a slow chorus and counter-clockwise adds a fast vibrato.MIX - Controls the blend between fully dry (clean) and fully wet (repeat only) echo sound. 12 o'clock is an equal mix of clean and echo.*Hint: The Mod knob works even when the delay time turned all the way down, allowing the Amnesia to function as an analog-flavored chorus pedal.Mode Toggle:MN3005 - Warm repeats with excellent fidelity and mild "bucket loss" where each of the delay repeats becomes a bit softer and more diffuse.SAD4096 - A very distinct tone where longer delay times have a pronounced distortion character. [This mode will sound like a spaceship a bit sooner than the others.]MN3208 - Audibly darker tone with soft and super murky repeats. Perfect for ambient pads and washes if you use your volume knob right.Power Supply:The Amnesia requires a 9V DC power supply with a 2.1mm pin, center negative. The Amnesia is not designed to be powered on supplies higher than 9V and does not use a battery. The Amnesia should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply. The Amnesia requires approx. 60mA.Please Note: The item displayed in the images may not be the actual item you receive.
