What is it?
Boss RV-3 Digital Reverb/Delay from compact series, made  in taiwan. Serial number on grey label points to june 1991. But since the units were apparently manufactured from 1994 to 2002 and the label was changed from pink to grey in early 1999, i think it’s safe to assume this follows similar error on serials as early taiwanese HH-2 Heavy Metals – being a decade off. This would mean that this unit is really manufactured in june 2001. Which makes a lot more sense.RV-3 is a second generation of Boss digital reverb pedals. Sharing the color with the ground breaking RV-2, but housed in standard compact pedal sizes enclosure. As it’s predecessor, the full blown SMD design was expected. Where the RV-2 had two boards stacked the RV-3 has only one. It is as tightly packed on both sides though. The circuit footprint is way smaller and the features are doubled. Who doesn’t like to live in the future.
