TENS jr.

TENS jr. is the little brother of TENS, which is modeled after the series of austrian high end studio spring reverbs from the early 1970s to early 1980s. It features TENS model 5 - tank A.
The properties of the reverb have been extended compared to the unit, it's been modeled after. So a single tank is stereo now and the range of decay times has been extended to 0.5 to 20 seconds.
The reverb's character can be altered drastically with the associated horizontal fader.
In contrast to classic spring reverbs found in guitar amps, organs or some synths, TENS jr. offers very high reverb density, fast build-up, and very low "boing" artifacts, making it sound almost plate-like.
