{"product_id":"befaco-bf-22-diy-kit","title":"Befaco BF-22 – DIY Kit","description":"\u003cp\u003eThe Befaco BF-22 DIY Kit contains the parts to build Befaco's BF-22 VCF, a dual high-pass\/low-pass Eurorack filter based on the Sallen-Key circuit of the early Korg MS-20. It is aimed at modular users who want that dirty, screaming early MS-20 character in their rack and who are comfortable with a medium-difficulty solder build.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo filter channels\u003c\/strong\u003e modelled on the early MS-20 Sallen-Key design, each switchable between high-pass and low-pass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo CV inputs per channel\u003c\/strong\u003e, with an attenuverter on the first\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage-controlled resonance\u003c\/strong\u003e, with attenuverters on both cutoff and resonance; Befaco gives the resonance a little more presence than the original\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLink switch\u003c\/strong\u003e that routes the output of channel one into the input of channel two\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutoff CV tracking\u003c\/strong\u003e over 3 octaves\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eA classic way to use it is to set the first channel to high-pass and the second to low-pass, then engage Link to run them in series for the familiar MS-20 band-shaping and squeal. Run separately, the two channels can process two different signals.\u003c\/p\u003e\u003cp\u003eBefaco is clear that the BF-22 also carries over the MS-20's noise floor, so it suits gritty, characterful patches rather than situations where a very quiet filter is needed. The kit includes everything needed for a finished module, including a power cable and four Befaco Knurlies M3 rack screws. Befaco publishes an assembly manual, user manual, schematic, BOM and an interactive build guide to support the build.\u003c\/p\u003e","brand":"Befaco","offers":[{"title":"Default Title","offer_id":55222310994259,"sku":"DIY005","price":125.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/4052\/1299\/files\/b9f98986-dd58-4f65-8fb7-f99596efbad6.jpg?v=1791364437","url":"https:\/\/www.voltmusicstore.com\/products\/befaco-bf-22-diy-kit","provider":"Volt Music Store","version":"1.0","type":"link"}
