This is a classic Lexicon piece. One of the best digital delay units ever built. It very easy to use and sounds awesome. There are buttons for set delay times, but there's also a knob that lets you adjust the time, but you won't know the exact time. There's also a "double time" button which does that, and also makes it sound grainier because it drops the sample rate. Great for thickening and doubling guitar tracks. If desired it can create some amazing gritty and grainy sounds even at 0 MS setting.
This unit was cleaned, bench tested and is in good working order.725
