Selling this, purchased two months ago, due to equipment upgrade. Operation confirmed. I believe this is the best in this price range. In particular, the ability to reproduce sound degradation gives it a very analog feel, which is great. Velcro is attached to the back, and the rubber feet have been removed. There are no scratches on the enclosure, but as it's an old effector, the lid screws are a bit rusty. Manufacturer's description: The DigiTech Obscura is a unique delay effect that can stretch, shrink, reverse, darken, degrade, and distort delay sounds. By combining these unique delay sounds with the repeat hold function, you can enjoy endlessly looping trip-like sounds and runaway noise. Of course, its performance as a normal delay is also top-class. The Obscura features a TIME control (tap tempo function also available) to determine the delay time, a REPEATS control (also used to set the repeat hold function) to set the number of repeats, a LEVEL control to adjust the delay level, two controls, TONE and DEGRADE, to correct the sound quality, a TAILS switch to set the On/Off of the function that naturally attenuates the reverb during bypass, a BYPASS switch (true bypass) to turn the delay On/Off, and a MODE selector to select any of the four delays. The delay modes available on the Obscura are analog delay emulator, tape echo emulator, lo-fi digital delay, and reverse delay.
