In 1972, when tape delays dominated the landscape, Don Buchla was exploring an emerging digital technology for delaying audio. The result was his Model 277. For reasons we still don’t know, it was never completed. Around the same time, Eventide was using similar technology to develop their first digital echo effects and the rest is history. What made the 277 special was Don’s modular approach: it was designed to interact with the other modules in his 200 synthesizer system, opening up possibilities for creatively patched effects that are beyond simple echos. The 277t is not an effect processor, it is a unit designed to patch effects by the user. Although Don never completed the device, he left behind an unfinished schematic. That schematic gave us a starting point for the 277t Signal Delay Unit, a new version closely based on his original idea.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-olk-copy-source=\"MessageBody\"\u003e\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003eThe 277 Signal Delay Unit was invented in 1972 and was one of the first digital delay lines ever made. A delay line passes audio through a series of clocked shift registers, with the clock speed determining the delay time.\u003c\/span\u003e\u003cbr\u003e\u003cspan\u003eOn its own, this simply delays the audio,but routing signals through different paths opens up further possibilities.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-olk-copy-source=\"MessageBody\"\u003e\u003cspan\u003eFor example, feeding the output back into the input creates repeating echoes, while placing additional processors in the feedback path allows for more complex effects.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-olk-copy-source=\"MessageBody\"\u003e\u003cspan\u003eModulating the clock speed can also create pitch-shifting effects. As such, the 277t should be considered, among its other functions, a centerpiece for building effects by patching it with other modules, rather than a modern delay effect module, which typically features a preconfigured signal path.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"TIPTOP AUDIO","offers":[{"title":"Default Title","offer_id":67043564912813,"sku":null,"price":277.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/files\/UntitledDesign-2026-10-16T123024.428.png?v=1792168327","url":"https:\/\/www.detroitmodular.live\/products\/tiptop-audio-buchla-200-series-277t","provider":"Detroit Modular","version":"1.0","type":"link"}
