Uniton Swissecho 2000 Update

Swissdoc updated his page on the Uniton Swissecho 2000

"I updated the page with some statements from Mr. Garcia about the AKG relationship and Uniton History. In addition I added some more sound samples from guitar amps with spring reverbs. Great how muffled they sound in comparision with the high-end tank of the Swissecho 2000."

Do a find for "comparison to guitar amps' for the demos when you get there, and Mr. Garcia of course for Mr.Garcia's comments.

The Uniton Swissecho 2000 Spring Reverb

via Swissdoc where you'll find additional details including some samples, the user manual, service manual & schematics.

"The Swissecho 2000 is a true stereo spring reverb with a bucket brigade delay (BBD) section to simulate the pre-delay and kind of early reflections missing in normal spring reverb systems. The BBD used is a TDA1022, actually 24 of them. They provide a delay time of 300 ms and by using a clock rate of 20.480 kHz a frequency response of about up to 10 kHz. The unit was sold with 12 TDA1022 as normal configuration, by adding some additional boards it could be extended.

The reverb tank uses 2 springs folded in a double Z configuration. The case is shielded by an anti-magnetic layer, most likely mu-metal. The tank as such looks pretty much like the tank used in the AKG BX15 reverb. I don't know if Uniton or AKG designed the tank, or who built them."
