Catalog booklet for the SHARP GF-490 “Searcher W” FM/AM stereo dual-cassette boombox, July 1982. The whole thing is built around one idea - the “倍速編集局” (High-Speed Editing Station): using two decks to record, dub, and mix tapes. Three advertising acts break down the features: ACT.1 covers basic playback and recording, ACT.2 introduces APSS-W for automatic program search across both cassettes, ACT.3 shows one-touch direct editing. The GF-490 was priced at ¥63,000.
