MXR Digital - Full 1280ms Digital Delay Line (100% Original MXR)

Description

Very clean with minimal surface marks.  This MXR Digital Delay Line has lived in my shock proof guitar rack for 36+ years.  She was last serviced 15 - 16 years ago.  At that time It was only sporting two memory cards for a total delay of 640ms.  I had managed to find several cards on eBay and maxed it out with all four card slots filled.  The label on the front may still say 320.  But I assure you with four cards it should say 640.  Now many question how 640ms equals 1280ms.  The first Knob is your DELAY TIME, the min counter clockwise setting is divide by 2.  At 12 o'clock straight up, it it what you normally read with the button selection.  At full clockwise it is 2 times the button setting.  For some reason MXR Chose to label them this way.  This unit does indeed have all four cards (See the last picture.) and is indeed a full 1280ms MXR Digital Delay Line.
Again this was serviced last between 15 and 16 years ago it was used for a very few times after that.  Just tested it out today and there was just a bit of scratchiness in the MIX pot.  ( This might go away with use as I have only fired it up a few times in the last 12 years.  I no longer play like I used to.)  Mostly Acoustic now!   If this did not go away.  I would recommend removing all the cards and contacts a general dusting internally cleaning, and spraying cleaner in all pots.  I did not perceive noise and hiss that would indicate the Capacitor needs to be replaced but these are still the originals.
