G-Storm Electro Spring Tank Reverb Driver ver 2.1 BLACK Eurorack Module Only

Spring Tank Reverb is an 4HP wide Spring Tank driver module for use in Eurorack +/-12v powered systems/cases sold separately. It works on a variety of Spring Tanks (sold separately) of various sizes. Features a CV control of the wet/dry mix.   NEW in version 2.1:  Added a jumper setting for quick and easy optimization of any size reverb tank – short, medium, or long.

WHO THIS IS FOR

Maybe you have a spring tank laying around and want to use it with your Eurorack system. I also have some DIY customers provide their own +/-12v power to the module to use a Spring Tank of their choosing in their guitar rig. You can also power/rack-up the module in something simple like a 4ms Pod series (sold separately).

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 | Rack screws and RCA cables are not included due to large assortment and highly varying individual preferences/needs, I personally use After Later Audio Rack Thumb Screws (sold separately). You will need powered eurorack system or +/-12v for eurorack pin header configuration. No spring tank included in this sale, be sure to check out my Ruby Short Spring Tank and Driver combo listing in my Reverb Store if you want both this module and my recommended Spring Tank together in one deal.

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

SPECs

Module Depth: 50mm | Current Demand: +12V 39mA, -12V 34mA, 5V not used

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.
