Digitalno krmiljen analogni kitarski efekt

MIKLAVČIČ, MATIC (author), Jankovec, Marko (mentor)

V pričujočem diplomskem delu je prikazano načrtovanje kitarskega efektnega pedala krmiljenega z mikrokrmilnikom, ki je osnovan na treh tradicionalnih kitarskih efektih, in sicer »overdrive« efektu »Tube Screamer« in dveh distortion efektih »Fuzz Face« ter »Jubilee«. Ugotovili smo, da je krmiljenje analognih kitarskih efektov z mikrokrmilnikom mogoče ter dokaj uporabno, kajti na ta način s shranjevanjem nastavitev potenciometrov v prednastavitve lahko z izdelanim prototipom nadomestimo več analognih kitarskih efektov istega tipa. V našem primeru smo v program vključili tri prednastavitve, vendar bi lahko z enostavno programsko razširitvijo v naš pedal vključili še več prednastavitev. Z združitvijo mikrokrmilnika s tremi analognimi kitarskimi efekti pa smo združili zvok klasičnih kitarskih efektov z enostavnostjo krmiljenja digitalnih vezij.

Abstract

This thesis focuses on a guitar effect pedal design, controlled by a microcontroller, which is based on three traditional guitar effect pedals. Those three are »overdrive« effect »Tube Screamer« and two »distortion« effects »Fuzz Face« and »Jubilee«. We concluded, that controlling analog guitar effects with a microcontroller is benefitial, because, by saving settings into different presets, we are able to substitute more than one pedal of same type with our prototype. In our case, our prototype has three presets, but with a simple program extension, we can program even more presets into our effects pedal. By connecting a microcontroller with three analog guitar pedals, we have merged the sound of classic analog guitar pedals with the simplicity of controlling digital circuits.
