Boss DS-1 Distortion, silver screw, long dash (DS-1), March 1980, made in Japan, black label with serial number 9200 (first digit "9" slightly smudged), PCB revision: DS-1 ET-28E, top-of-the-line Toshiba chip: TA7136AP. This is the most sought-after "silver screw/long dash" version in terms of sound—the most "juicy," saturated with charmonics (unlike the earlier versions, which are much brighter and not as saturated). Online, on a well-known video portal, you'll find comparisons of the 1978 vs. 1984 version (DS-1 ET-28F). The 1984 version has the same chip, but slightly changed components (foil capacitors, J-fett transistors, etc.).
