{"product_id":"diode-ladder-vcf-6hp","title":"Diode ladder VCF (6HP)","description":"\u003cp\u003eAn updated version of my old diode-ladder filter - now shrinkified so that it fits into 6HP rather than 8HP.\u003c\/p\u003e\n\u003cp\u003eIt is, as it's name suggests, a filter which utilises a ladder of diodes and capacitors to work its magic. It's surprisingly versatile, and with voltage-controlled resonance as well as cutoff you can make this sound as gnarly as you like. Or not.\u003c\/p\u003e\n\u003cp\u003eThere are two trimmer pots on the rear of the board which you can use to adjust the response of the filter.  The CV trim will be pre-adjusted so that with the cutoff pot fully counter-clockwise there'll be nothing passing through the filter. There's also a V\/octave trimmer which you can use to alter the cutoff CV response - I generally leave this alone but you can fiddle with it to your heart's content.\u003c\/p\u003e\n\u003cp\u003eIf you want something potentially nasty sounding then this could be for you - if you'd prefer something more mellow then the state-variable or YaVCF filters may be a better fit; they're all based around the LM13700 dual OTA but have slightly different topologies.\u003c\/p\u003e\n\u003cp\u003eThis initial run will be pre-built only, but I plan to offer partial builds starting with the next board run.\u003c\/p\u003e","brand":"York Modular","offers":[{"title":"Default Title","offer_id":56718114914682,"sku":"DIODE-LPFv2","price":39.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0274\/7115\/1213\/files\/IMG20260326174035.jpg?v=1774548561","url":"https:\/\/www.yorkmodular.co.uk\/products\/diode-ladder-vcf-6hp","provider":"York Modular","version":"1.0","type":"link"}
