****IMPORTANT WARNING!**** If your unit has a 3 prong power cord, it must be plugged into a grounded (3 prong) AC outlet. DO NOT DEFEAT THE GROUND ON THIS DEVICE!! If there is a failure within the unit, the ground connection is your only protection against dangerous voltages! If your unit came with an external power adaptor, use only this supplied power pack. Using the wrong power adaptor may damage your unit and void your warranty. Your Deluxe Memory Man with chorus/vibrato is designed with state-of-the-art solid state circuitry to give you years of high quality, trouble-free performance. Connect your guitar to the INPUT jack, and the OUTPUT jack into the input of your amp. Your Memory Man can be used in combination with other effects devices - experiment to develop your own unique sound. The bypass footswitch on top of the unit allows you to switch the effect in and out. Unmodified signal is always available at the DIRECT OUT jack. Set the LEVEL control so that the OVERLOAD LED blinks on with the loudest notes you play, but does not come on very brightly or too frequently. Overdriving the unit will cause distortion. The BLEND control allows you to vary the mix of direct and delayed signals; it is set to the center position equal levels of both. FEEDBACK provides delay repeats, or multiple echoes. If set very high, runaway oscillation will occur. Fairly high feedback with short delay settings produces a reverb effect. The DELAY control determines the time between direct and delayed signals, and between the repeats when feedback is used. Strange, eerie and unusual pitch-shift effects can be produced by changing the delay while playing, especially while using feedback. The CHORUS/VIBRATO control introduces a modulation in the delay time: slow for chorus, faster for vibrato. This produces a "Doppler" pitch shifting in the delayed signal. A rich, vibrant chorus effect is produced with the switch set to CHORUS, delay fairly short, blend at the center, chorus set high, and feedback fairly high. When you determine the control settings for your favorite effects, make note of them so you can quickly set up the unit before playing. Unplug after use. Avoid operating near moisture. Rock-n-Roll!
