The principle of the \"substitution box\" is to group multiple values of the same component type into a single enclosure, allowing quick comparison of options without repetitive manipulations on the breadboard. Within this range, there are various models (resistors, diodes, ceramic capacitors, electrolytic capacitors, transistors), and this version is specifically dedicated to \u003cstrong\u003efilm capacitors\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eWho Is It For and What Are Its Uses in Audio, Synths, and Effect Pedals?\u003c\/h3\u003e\u003cp\u003eThis substitution box is aimed at designers, repairers, and DIY enthusiasts who want to speed up value selection: effect pedal manufacturers, modders, preamp designers, synth module developers, or anyone prototyping analog circuits. In audio, changing capacitance can alter a filter's cutoff frequency, the response of a tone control, the amount of bass passing between stages, or the behavior of a compensation network.\u003c\/p\u003e\u003cp\u003eIt is particularly useful when you want to compare \"by ear\" (playing and switching a value), but also when validating a design with an oscilloscope or multimeter. Rather than pulling out a component box, bending leads, inserting, removing, and repeating, you conduct your tests keeping the same wiring and only changing the selected value.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cstyle\u003e@media(max-width:632px){table[data-wb-spec]{display:grid;grid-template-columns:minmax(0,1fr) minmax(0,1fr)}table[data-wb-spec] colgroup{display:none}table[data-wb-spec] tbody,table[data-wb-spec] tr{display:contents}table[data-wb-spec] td{display:block;overflow-wrap:anywhere;grid-row:var(--wb-l);background-color:var(--wb-lb)}table[data-wb-spec] td[data-r]{grid-row:var(--wb-r);background-color:var(--wb-rb)}table[data-wb-spec] td[colspan=\"2\"]{grid-column:1\/-1}table[data-wb-spec] td:empty{display:none}}\u003c\/style\u003e\n\u003ctable data-wb-spec style=\"width:100%;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003ccol style=\"width:25%\"\u003e\u003c\/colgroup\u003e\n  \u003ctr style=\"background-color:var(--wb-neutral-50);--wb-l:1;--wb-r:2;--wb-lb:var(--wb-neutral-50);--wb-rb:transparent\"\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eUse\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eelectric guitar\u003c\/td\u003e\u003ctd data-r style=\"text-align:left\"\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\u003ctd data-r style=\"text-align:left;font-weight:var(--font-body-weight-bolder)\"\u003eBlack\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"CopperSound","offers":[{"title":"Default Title","offer_id":54359670227219,"sku":"422699","price":79.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/b512219dc22a33c744c7484c2fc014928138b60b_FILLING_COPSBFC.jpg?v=1789382163","url":"https:\/\/woodbrass.shop\/products\/coppersound-substitution-box-film-capacitor-422699","provider":"Woodbrass.com","version":"1.0","type":"link"}
