FEATURES

Pots: Tone, Feedback, CV of wet/dry amount, Initial Wet/Dry amount.  Drive trimmer for accommodating various spring tanks.  Jumper setting for quick and easy optimization of any size reverb tank – short, medium, or long. Signal strength LED indicator. RCA jacks on the back of the module for mounting tank internally in the case. 

INCLUDED 10-to-16 pin ribbon cable. 

NOT INCLUDED | Reverb tank and RCA cables (sold separately). M2.5 or M3 (Doepfer standard) Phillips-head basic zinc rack screws are only provided on special request. Why do I do this? To cut down on rack screws that are wasted in the universe. What's it gotta be? Thousands? Hundreds of thousands? Unused, unwanted. You know the ones I mean | wrong size, wrong color, cheap junk tin, top slot-stripping, rack-rashers, wrong thread count, wrong length, wrong political party, etc. I use thumb screws in 2 sizes myself. So yeah, if you request some M3's from me, I will probably pull the ones from other companies boxes in my closet. You're welcome :D

CHOOSING A TANK

GROUNDING CONNECTORS (5TH character in tank model #) Type  A or C is best.  SIZE & NUMBER OF SPRINGS | Short, Medium, or Long length (approx. 16”).  2 or 3 number of springs are known to work well. INPUT IMPEDANCE | (2ND character in tank model #) | any except “F” (1475 ohms, has not been tested).  OUTPUT IMPEDANCE | (3RD character in tank model #) |“B” known to work best, all others untested.  TANKS THAT WERE TESTED AND KNOWN TO WORK WELL | Vintage Folded Line, Medium size, 3-spring, as those used in a Roland Space Echo | Accutronics BAB3C1B Medium size, as taken from a Fender Sidekick Amp | | Accutronics 4AB3C1B Long size 16”, 2-spring. MOST RECOMMENDED | Ruby Tubes 2EB2C1B short size 9”, 2-spring, has plenty of drip and feedback with a size to fit many different case scenarios.  TANKS REPORTED NOT WORK WELL | 8BB2C1A

Note: due to RCA jack placement and chunkiness of some RCA plugs, it may not be feasible to mount this module on the bottom row of your system rack.  Please refer photos.  As a workaround you might try a cable with 90-degree RCA plug ends.  Another possibility would be to carefully trim away the strain relief section from the RCA connector without damaging the wiring wrap – as seen in the photo.
