Two rare Pioneer silver era effect units in one auction (1980–82) – both featuring the legendary blue fluorescent displays. 1) SR-303 - stereo reverb amplifier: spring reverb with adjustable time and depth, 2 effect modes, effects can also be recorded onto tape. 2) RG-2 - RG dynamics processor (range expander), restores compressed dynamics in recordings; very rare in Europe – only a few units available continent-wide at the same time. A pair from one collection, stored together – a great opportunity to complete the Pioneer "blue line" set (compatible with Pioneer silver era amplifiers, tuners, and tape decks). Together, these units sell in Europe for about €600 https://www.hifishark.com/model/pioneer-sr-303 https://www.hifishark.com/model/pioneer-rg-2 From a private audio collection – carefully stored. Units have not been tested – this is reflected in the starting price. Visual condition shown in photos. Only the devices are included. More Pioneer units from the same era will be available in our auctions. Follow our other auctions as well – we are selling an entire audio collection.
