TipTop Audio

Buchla Model 292t Quad Low Pass Gate


Welcome to the Buchla & Tiptop Audio 200 series project. In this project Buchla has teamed up with Tiptop Audio to resume the production of Don Buchla’s 200 series and convert it to Eurorack standards. These extremely rare pieces of equipment made almost half a century ago will once again be available, and this time to a wide audience.

TipTop Audio spent a great deal of time together with the folks at Buchla to define what is a ‘good sounding’ Vactrol. All the Vactrols in the 292t and now in Buchla products are made by Tiptop Audio and are obviously at the heart of the 292t, eight of them per module to be precise.
