Title link takes you to more shots via this auction."This is a rare bird indeed. This is part of a modular effects system that Sequential Circuits developed in the 80's. This is a real reverb tank with springs inside."

Update via the comments:
"thats just the reverb tank.. you need the 518 MODULE to drive it... otherwise you just have a paperweight"
Update2:link
"The Model 518 Reverb includes a compact, rackmount six spring delay line, and a three-band equalizer which filters the input to and output from the reverb unit. The LP (lowpass) filter limits frequencies above its setting from 200Hz to 20 kHz. The HP (highpass) filter limits frequencies below its setting from 20Hz to 2 kHz. The MID (midrange) band filter has separate frequency (50 Hz to 5 kHz) and EQ boost/cut controls. For example a typical use would be to use the HP filter to prevent a bass drum from dominating the reverb. The module also features automatic limiting which reduces undesirable spring colorations. It contains a PEAK LED indicator for optimizing signal levels."

I was watching this and thought I missed out on a cool deal. Thanks for the information.
ReplyDeleteOf course the twin springs were probably worth the auction cost anyhow. Or a clone of the driver could be built.

FYI i think i have about 5 of these springs on my shelves. every home organ has these ... i've taken apart enough to know.
ReplyDeletethey're the very very standard Accutronics 18" assembly, removed from its enclosure to fit inside a rack box.
unless the 518 module is present, you're looking at about 50 dollars worth of springs in a 50 dollar chassis, which makes the "sequential circuits" printing worth about six bucks ... so i guess this bidder did well. i'd figure that pad printing to be woth at least ten.
